Insect cocoon on wall

A cocoon is a protective casing, usually made of silk. This casing protects the larval, or immature stage, of an insect from the elements, such as extreme temperatures. Inside the cocoon, the larva, which is often wormlike, will undergo metamorphosis and emerge as an adult, a process common among insects and other arthropods.

Adult fleaswhich pet owners may see on their dogs and cats, can lay up to 50 eggs a day. After hatching, these eggs produce worm-like larvae. Inside the home, these larvae may be found in carpet or other areas frequented by pets. The larvae form cocoons, and in weeks will transform into adult fleas. These cocoons are nearly impossible to see. Butterflies and moths are perhaps the most commonly known insects that build cocoons.

Their larvae, which are caterpillars, are voracious eaters.

Caterpillars spin silk, and this silk is used to form the cocoon for the pupal stage of development — the final stage before adulthood. Some moths, such as the clothes mothmay find their way into homes.

These moths feed on common household items, such as fibers in clothes and grains or other foods in the kitchen. If necessary, these moths may form cocoons and pupate in your house.

A pest control professiona l can help identify the cocoon and the species of moth that created it. These insects resemble moths, and they spend most of their lives in or near bodies of water like lakes, rivers and ponds. The larval stage of these insects lasts up to two years, during which they feed on algae or other small organisms found in the water in which they live. Larval caddisflies spin silk and use this material to make cocoons or casings around twigs and other particles in the water, like sand and gravel.

Typically, caddisflies pupate from the winter through the early spring. Some species of parasitic wasps attack hosts and use these host insects as nutrients for their young throughout development.

The stage at which the wasp attacks varies with species, some attacking eggs, others choosing larvae or adults. Common host insects include aphids, caterpillars, sawflies, beetles and flies.

After larval wasps have emerged from their eggs within their hosts, they spin silk to form cocoons either inside, around or nearby their hosts.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Confusing because they do resemble caddisfly larvae cocoons more so than those of their own family Tineidae. Sort blurb Here :. The case in the above image is covered with fine sand and debris, and superficially resembles a caddisfly case. When crawling, the larva's head, thorax, and three pairs of legs protrude out of the case, and drag it along. According to Internet sources, the larva feeds on a variety of material, including hair, fur, silk, felt, feathers, woolen clothing, upholstered furniture and carpets.

It apparently prefers darkness and soiled clothing, and is not fond of synthetic fabrics, such as nylon and polyesters. This is probably caterpillar of one of the moth species from family Psychidae. They larvae looks like Trichoptera larvae and builds similar cases out of silk and material found in nearby surroundings.

Melissa Geib Oct Found a picture of a possible cocoon.By fakenameApril 7, in Pattaya Forum. Just wondering if someone knows the name of the insects, that attach themselves to the ceilings and walls of homes.

This morning just noticed that there were a hundred or more on the walls. They look like a worm, but then make a cocoon, which usually hangs by a thread, like a spider web. I see them all the time, but today, there were more than normal. I tried to Google something up, but just too many to go through. I guess they are harmless, but would just like to be on a first name bases with them, since they are living in my home. They are harmless.

I pick them off the wall every time I spot one, otherwise they continue on and attach themselves to the ceiling, Where they or the remains of whatever process is going on remain forever! I hope someone knows more, as I've often wondered what is going on with them.

Do they turn into some kind of moth? I had one that opened and turned into Stephan Harper and then sold Canada's Oil sands to the Chinese. They are cocoons for a small moth called casebearer moth, there has been other posts about them in the past. They're generally harmless but a nuisance as they multiply quickly. Often they hide behind pictures or furniture. I usually just pick them off whenever I see them. That is strange.

I have seen and had the cocoons, many of them, in different locations, but never noticed that kind of moth around. Also the cocoons don't seem to look exactly like that - no "head" so visible - but that probably is due to higher quality in the image on the picture than on my eyes. I think Phil is right, but I also have never seen any moths, so dont know what they eat, and where they lay their eggs. I guess the head only pops out at certain times, when they are on the move.

The cocoon is left behind after the moth is gone, so obviously there you will not see any "head", but if you find a live one just hold it for a moment and you'll see the head move. I've had silverfish in the boot of my car here in Thailand I think they liked the damp carpet fixed the leak and got rid of carpet.

Have you noticed small greyish to white colored bugs hanging on your walls or ceiling? Or maybe it looks like some kind of egg sac? What you are likely seeing is a cocoon-like case, with an insect hidden inside.

Dust Worms are another common name for these creatures. Despite ultimately transforming into a moth, it is not typical to have significant numbers of moths visibly flying about the house.

If this is the case, it is more likely you may have an infestation of Indian Meal Moths. Like people, insects have basic needs such as food and shelter, that must be met in order to survive. Their diet consists of old spider webs, dead insects, and even human hair. Part of the reason these insects are found stuck to walls and ceilings is that they have climbed up there to be closer to the cobwebs they feed on.

It's very common to find Plaster Bagworms and Household Casebearers attached to the exterior stucco, vinyl or wood siding of homes as well. Because both their diet and the material used to create their cocoon is basically tiny bits of organic material, thorough and consistent cleaning can remove both the food and shelter they need to survive and result in a decreased population.

This, however, can be a bit difficult in areas such as garages, carports, patio, and lanai areas. Nevertheless, sweeping down cobwebs, and blowing out accumulated debris in garages and porches will help prevent a thriving Casebearer population. Another good tip for preventing Plaster Bagworms is to reduce outside lighting. Ultimately, these little creatures are moths. Moths are notoriously attracted to porch lights.

If moths are attached by a light left on in the garage, or a security light on the side of the house, you are attracting them to your home. It is ultimately these adult female moths that will lay the eggs that eventually turn into the annoying little egg sac-like creature stuck to your ceiling. Obviously, there is little that can be done in this regard in outside areas. They are certainly capable of surviving inside homes. Plaster Bagworm populations will be higher in homes where the inside temperature is kept above 80 degrees.Photo By: Courtesy of P.
