Can anyone identify this bug?


Spotted in Czech Republic. Our office was hit with cockroach infestation, so I'm afraid if I haven't carried one home.


It is German cockroach (Blattella germanica) with two dark parallel streaks on it's pronotum.

The one in your picture is a lady laying her ootheca.

It is a pest.

Here's it in different stages of life cycle.

Things you might like to know:

Blattella germanica occurs widely in human buildings, but is particularly associated with restaurants, food processing facilities, hotels, and institutional establishments such as nursing homes.

German cockroaches are omnivorous scavengers. They are attracted particularly to meats, starches, sugars, and fatty foods. Where a shortage of foodstuffs exists, they may eat household items such as soap, glue, and toothpaste.

The German cockroach reproduces faster than any other residential cockroach, growing from egg to reproductive adult in approximately 50 - 60 days.

Heat Riser Gasket: 111251263A
As far as mufflers go I think they changed in 1955-1956.

Following is my original post:

I was told that this muffler was NOS for a 36hp bug. When I compared it to my existing 1956 36hp muffler, it has a couple of differences
**It has (2) manifold heat tubes. My existing and also the ones sold on Wolfsburg and JBugs show only (1)
**The larger diameter tubes coming out of the bottom which connect back toward the engine are curved down or bent and the ones coming out of my stock muffler are perfectly straight back.
Also, the heat tubes have a small "kink" in them is that okay?

Personally easiest way I have to tell 25/36 HP from 40 HP and later is the heat riser gasket areas.

Just a few examples from the gallery:

Personally easiest way I have to tell 25/36 HP from 40 HP and later is the heat riser gasket areas.


. tried to put a 36 horse muffler on a stale air, 1961 engine and nothing lined up. is great you say, they are different, because of the heat riser .. and now, I know from experience, that they are different.

Insects in the City

Conenose bug adults are about one inch-long, and active primarily at night.

Conenose, or kissing bugs (Triatoma sp.), are blood-feeding insects that are an occasional problem in Texas homes. Although conenose bugs bite humans and regularly transmit disease in parts of Latin America, for most U.S. victims the worst consequence is redness and itching at the site of the bite.

Identification

Conenose bugs are recognized by their elongated or “cone-shaped” head, prominent antennae, pear-shaped body, and spindly, stick-like legs. The body is black or dark brown, 1 to 3 cm (1 to 1 ½ inches) in length, with 12 orange spots ringing the outer edge of the abdomen. Long, beak-like mouthparts arise from the front of the head and are held under and against the center of the body when not in use.

Biology

Conenose bugs feed exclusively on the blood of vertebrate animals. Although generally rare, they are most common around animal nests or pet resting areas, emerging at night to search for blood meal. Their bites are gentle and painless, and usually occur while the victim is asleep. They are generally unable to bite through clothing. On humans, blood meals are sometimes taken from the tender areas of the face (hence the name “kissing bug”). Other sites of attack (in order of decreasing frequency) include the hands, arms, feet, head and trunk. Victims are frequently unaware of the bites until the following morning when unexplained reddened areas may be present on the skin of the arm or face.

Importance

Conenose bugs can be carriers of the protozoan parasite, Trypanosoma cruzi, that causes Chagas’ disease–a serious disease of humans that occurs most commonly from Mexico to South America. For many years very few human cases of Chagas’ disease were recorded in Texas (five cases since 1955) however recent attention by researchers appears to be turning up more human cases than previously thought possible (8 Texas-acquired cases in 2013, according to the Texas Department of State Health Services). Cases among dogs are more common (over 200 reported cases in 2013), especially in southern regions of Texas. While overall frequency of Chagas transmission to people in Texas is still relatively rare, people should be careful when handling bugs and should take steps to eliminate these bugs when found indoors.

Natural reservoirs of the Trypanosoma parasite are maintained in nature among small vertebrate animals, notably armadillo, opossums, rodents, bats, cats and dogs. Conenose bugs commonly feed on several different hosts during their development. Nymphs feed on an infected host and become infected themselves. The parasite can then be transmitted during subsequent blood meals to an un-infested host. While feeding, the insect may defecate on the skin of its victim. When a victim touches the feces, parasites may be transferred to the site of the bite, to the eye or to the mucous membranes around the mouth or nose. Transfer of the parasite may be hastened by scratching the bite. Chagas’ disease is difficult to diagnose, but is sometimes indicated in the initial stage by a swelling on one side of the face, known as the sign of Romaña.

Control

Conenose bugs are nocturnal and may be attracted to nighttime lights. In this way, solitary individuals may enter a home. A single conenose bug in the home is not necessarily cause for alarm. However the presence of nymphs (unwinged bugs) or numerous adult conenose bugs in your home suggested that a breeding population may be established nearby. Under these circumstances control may be justified.

Conenose bug infestations are likely to be more common in poorly constructed homes. Good sanitation and tight building construction tends to limit conenose bug infestations. Destroy trash piles, bird and animal nests and burrows. Control and exclude rodents and birds from the house. Seal exterior cracks and openings into buildings and keep chimney flues closed tightly. Inspect and seal any openings from crawl spaces into the house sub-flooring. Check pets for signs of feeding and examine pet houses.

Insecticides can effectively control conenose bugs. Treat room corners and edges, window and door frames, pet houses, and other suspected entry points with a pesticide labeled for these sites. Few household insecticides are labeled specifically for use against conenose bug however products intended for indoor use against cockroaches or other indoor pests can be used. Look for products containing one of the pyrethroid insecticides: permethrin, bifenthrin, cyfluthrin, esfenvalerate or lambda cyhalothrin.

Consider using a licensed pest control professional for conenose bug control. Besides their experience in treating insect problems, professionals are better suited to assist you with control of possible rodent or pest bird problems. A professional can also point out ways to pest proof your home. The most effective professional products for conenose bug control include wettable powder or microencapsulated formulations of pyrethroid insecticides such as cypermethrin, lambda-cyhalothrin, deltamethrin, or cyfluthrin.

Harmonia axyridis is a typical coccinellid beetle in shape and structure, being domed and having a "smooth" transition between its elytra (wing coverings), pronotum, and head. It ranges from 5.5–8.5mm in size. The common color form, f. succinea, is orange or red in colouration with 0–22 black spots of variable size. The other usual forms, f. conspicua and f. spectabilis, are uniformly black with, respectively, two or four red markings. The pronotum is white with variable black patterning, ranging from a few black spots in an M formation to almost entirely black. The underside is dark with a wide reddish-brown border.

However, numerous other forms have also been recorded. Extreme forms may be entirely black, or feature complex patterns of black, orange and red.

The large size of this species is usually the first clue to its identification. [5] [6] Despite variation, this species does not generally overlap in pronotal or elytral pattern with any other species, except in unmarked orange or red forms. In Europe it is similar to the much smaller Adalia decempunctata, while in America it is similar to the much narrower Mulsantina picta and spotless forms of Adalia bipunctata. When identification is difficult, the underside pattern usually enables a reliable conclusion. [1] Identification is most simple for the common forms, while less common varieties may take longer to identify. [7] They always have reddish-brown legs and are obviously brown on the underside of the abdomen, even in the melanic colour forms. [3]

Harmonia axyridis is native to eastern Asia from central Siberia, Kazakhstan, and Uzbekistan in the west, through Russia south to the Himalayas and east to the Pacific coast and Japan, including Korea, Mongolia, China, and Taiwan. As a voracious predator, it was identified as a biocontrol agent for aphids and scale insects. Consequently, it has been introduced into greenhouses, crop fields, and gardens in many countries, including the United States and parts of Europe. The species is now established in North America (United States, Canada, Mexico), Central America (Guatemala, Honduras, Costa Rica, Panama), South America (Venezuela, Colombia, Ecuador, Peru, Argentina, Chile, Brazil), Europe (Italy, Spain, the United Kingdom, Denmark, Sweden, Norway, Finland, the Netherlands, Belgium, Luxembourg, France, Germany, the Czech Republic, Slovakia, Hungary, Romania, Serbia, Croatia, Bosnia and Herzegovina, Poland), Israel, and South Africa. [3] [8]

North America Edit

This species became established in North America as the result of introductions into the United States in an attempt to control the spread of aphids. In the last three decades, this insect has spread throughout the US and Canada, and has been a prominent factor in controlling aphid populations. The first introductions into the US took place as far back as 1916. The species repeatedly failed to establish in the wild after successfully controlling aphid populations, but an established population of beetles was observed in the wild near New Orleans, Louisiana, in about 1988. In the following years, it quickly spread to other states, being occasionally observed in the Midwest within five to seven years and becoming common in the region by about 2000. The species was also established in the Northwest by 1991, and the Northeast by 1994, aided by additional introductions from the native range, rather than just reaching there from the Southeast. Reportedly, it has heavily fed on soybean aphids (which recently appeared in the US after coming from China), supposedly saving farmers vast sums of money in 2001.

Worldwide propagation Edit

Worldwide routes of propagation of H. axyridis were described with genetic markers in 2010. [9] The populations in eastern and western North America originated from two independent introductions from the native range. [9] The South American and African populations both originated independently from eastern North America. [9] The European population also originated from eastern North America, but with substantial genetic admixture with individuals of the European biocontrol strain (estimated at about 40%). [9]

This species is widely considered to be one of the world’s most invasive insects, [10] [11] partly due to their tendency to overwinter indoors and the unpleasant odor and stain left by their bodily fluids when frightened or crushed, as well as their tendency to bite humans. [10] In Europe it is currently increasing to the detriment of indigenous species, [10] its voracious appetite enabling it to outcompete and even consume other ladybirds. [10] The harlequin ladybird is also highly resistant to diseases that affect other ladybird species, and carries a microsporidian parasite to which it is immune, but that can infect and kill other species. [11] Native ladybird species have experienced often dramatic declines in abundance in areas invaded by H. axyridis. [12] In 2015, it was declared the fastest invading species in the UK, spreading throughout the country after the first sighting was confirmed in 2004. [13]

In addition to its household pest status, [14] the harlequin has been reported to be a minor agricultural pest that is inadvertently harvested with crops in Iowa, Ohio, New York State, and Ontario. [15] This can cause visible and sensory contamination. [16] Contamination of grapes by this beetle has been found to alter the taste of wine. [17]

Harmonia axyridis becomes dormant in cooler months, though it will move around whenever the temperature reaches about 10 °C (50 °F). Because the beetles will use crevices and other cool, dry, confined spaces to overwinter, significant numbers may congregate inside walls if given a large enough opening.

Large aggregations are often seen in autumn. The beetles have pheromones to signal to each other. However, many aggregation cues are visual, picking out sites at both long (light-coloured structures that are distinct from their surroundings) and short (pre-existing aggregations to join) distances. Non-volatile long-chain hydrocarbons laid down by previous aggregations also play a significant role in site selection. Both visual and hydrocarbon cues are more important than volatile pheromones.

They often congregate in sunlit areas because of the heat available, so even on fairly cold winter days, some of the hibernating beetles will "wake up" because of solar heating. Large populations can be problematic because they can form swarms and linger in an area for a long time. The beetles can form groups that stay in upper corners of windows. This beetle has been also found to be attracted to dark screening material for its warmth. It has good eyesight it will return from a location to which it is removed, and is known to give a small bite if provoked. [18]

Harmonia axyridis, like other ladybeetles or ladybirds, uses isopropyl methoxy pyrazine as a defensive chemical to deter predation, and also carries this chemical in its hemolymph at much higher concentrations than many other ladybeetle species, along with species-/genus-specific defensive compounds such as harmonine. These insects will "reflex bleed" when agitated, releasing hemolymph from their legs. The liquid has a foul odour (similar to that of dead leaves), a bitter taste, and can stain porous materials. Some people have allergic reactions, including allergic rhinoconjunctivitis when exposed to these beetles. [2] Occasionally, the beetles will bite humans, [2] presumably in an attempt to acquire salt, although many people feel a pricking sensation as a beetle walks across the skin. Bites normally do no more harm than cause irritation, although a small number of people are allergic to bites. [19]

These beetles can be difficult to identify because of their variations in color, spot size, and spot count of the elytra. The easiest way to identify H. axyridis f. succinea is to look at the pronotum and see whether the black markings look like a letter "W" or "M". This species has more white markings on the pronotum than have most native North American species, though this feature is not useful when attempting to separate it from species in other parts of the world.

Life cycle: mating, eggs, five larval stages, pupa and newly emerged adult


Can anyone identify this insect?

Thanks for link. Looks very similar! I'm in Italy tho and from the description that one is only found in N America.

I googled 'italian beetle long horns' . looks like it's a type of longhorn beetle.

Whatever it is I guarantee my hand would not be that close to it. Lol totally not a bug fan

Message withdrawn at poster's request.

That hand is my 12 year old sons! Not mine. I was cringing behind the phone. To be fair, I'm not an insect fan but it was pretty impressive - you could hear its footsteps! Thanks for replying all x

A link to a picture would be good.

Right now it’s what we call a “no-see-um”.

Thanks. I’m really trying to find a link I can use to upload the image. Any idea where is it?? I’m using the mobile site. Anyway, this ‘thing’ is black, really flat and broad, has a dried up skin with fish-like scales, really small…about an inche long. Has no legs and has a curved tail. Has one antenna. Anyone know how I can upload an image?

If you post a photo on photobucket, and then copy the link to this site, we can see what you see.

filmfann ( 48649 />) “Great Answer” ( 0 />)

Possibly a stink bug or one of his cousins. I live in upstate NY and see a lot of them inside the house now. Your description of no legs, a curved tail and only one antenna doesn’t quite match. But the size, color and scales do.

gailcalled ( 54584 />) “Great Answer” ( 1 />)

No legs and one antenna? Maybe you sat on the poor thing and now it will be harder to identify because it is maimed. lol
Fish scales, no legs, maybe a Silverfish?

The Behavior Response of Pill Bug (Rollie Pollie) in Moisture, Scent,and pH level

Abstract

This experiment was used to test animal behavior. We tested the response pill bugs had to different environments in three different experiments: moist v/ dry, unscented v/ scented, and acidic v/ neutral. By setting up environment chambers that portrayed those environments, we found that pill bugs prefer dry over wet, unscented over scented, and neutral over acidic.

Introduction

When one thinks of behavior, it is generally linked to action. Behavior is defined by action. Animal behavior, in short, is the action of the animal. The study of animal behavior is known as ethology, which has two starting points: ultimate and proximate questions. Ultimate questions address the "why" of the behavior. Why does this certain behavior happen? What does it accomplish? Examples of an ultimate question would be "Why do birds sing?"or "Do louder bird songs attract more mates?" Proximate questions address the "how"of the behavior. An example of a proximate question would be "How do birds know when to sing?" Some actions are fixed action patterns, meaning a certain action happens at an exact time over and over again. In animals, these actions have never been taught to them, but are instinctive. Mating calls are often fixed action patterns. For example, when peacocks mate, the male tries to impress the female by showing off his colorful feathers and doing a sort of dance. Animal behavior is not all instinctive. Imprinting is a time in a young animals life where the animal becomes attached to a parent and begins to copy certain characteristics from it. For example, geese, ducks, and some other animals can imprint on humans, or other animals outside of their own species. An ultimate cause could be that imprinting is essential to survival because of the goose's need for a parental figure. An proximate cause could be that it is an instinctive action to imprint on another living being. Kinesis is the nonspecific movement of an animal. The pill bug moved around randomly until it found a desired environment. Taxis is the direct movement in response to a stimulus. For example, birds migrating south would be a taxis movement because the cold climate is the stimulus to the migration. Classical conditions are where an animal associates something with an idea and its body responds to it. Ivan Pavlov's dogs are an example of classical conditions. Pavlov trained his dogs to come for food by ringing a bell. Whenever the dogs heard a bell ringing, they associated it with food and their mouths began to salivate. Operant conditions uses reinforcement to either increase or decrease a behavior. For example, a dog is given treats for obeying commands, while it is reprimanded for disobeying commands.

Hypothesis

Part 1: Moisture v/ No Moisture

If the pill bugs are given the option of two environments: one moist and one dry, it will choose the former because they are normally found in more damp places.

If the pill bugs are given the option of two environments: one scented with vinegar and one not scented, it will choose the latter because the pill bug's normal environment doesn't usually have any particular scent.

If the pill bugs are given the option of two environments: one acidic and one neutral, then it will choose the latter because the pill bug's normal environment is at a neutral pH level.


LOUD bug or frog. Can anyone identify?

A friend of mine sent me this video of a very strange sounding insect making a mating call or something near her place in the Stuart area. I posted it because think it's very strange myself and even I don't know what the heck it is. Definitely not a Cicada since experts on a Cicada site I linked to said it was either a frog or katy-did. Any guesses?

I was wondering where I dropped my cell phone, it was set to vibrate! Thanks!
No idea what that was if I wasn't clear by my first line!

It sounded to me like an automatic camera shutter.
I guess it sounds a little like a cell phone ring too.

Since I don't hear any other noises like that on the video I guess it is more likely to be a frog. If it were a katy-did or insect I would think their might be more than one. Know I never heard a bug or frog for that matter, that sounded mechanical and loud like this one.

Seriously, that sounds just like my mobile phone if it's left on a table and a call comes in while it's set to vibrate.

Certainly not like any frog I ever heard, but there are an awful lot of different types of frogs.

Anthonomus grandis
Boheman, 1843
Wikispecies has information related to: Boll weevil
The boll weevil (Anthonomus grandis) is a beetle measuring an average length of six millimeters, which feeds on cotton buds and flowers. Thought to be native to Central America, it migrated into the US from Mexico in the late 19th century and had infested all US cotton-growing areas by the 1920s, devastating the industry and the people working in the American south. During the late 20th century it became a serious pest in South America as well. Since 1978, the Boll Weevil Eradication Program in the US has allowed full-scale cultivation to resume in many regions.
