Good Morning, Please see photos of bugs collected from carpet with rice like cocoons?? Can you identify what the bug is and what the rice bits are. There are areas of carpet which have clearly been eaten and we need to identify the problem.
Many thanks

Case Bearing Clothes Moths and Woodlice

Casemaking Clothes Moths and Woodlice

Hi Ashley,
The “bugs” are Woodlice or Pillbugs, and though they might be a nuisance indoors, they are not eating your carpet.  They are attracted to damp conditions.  The rice like cocoons appear to be the cases of Casemaking Clothes Moths,
Tinea pellionella, a species that will eat wool rugs and clothes and we believe that is the source of the damage.  According to BugGuide, the larvae feed on:  “Feed on wool, feathers, fur, hair, upholstered furniture, leather, fish meals, milk powders, lint, dust or paper.”  The larvae, not the adult moths, are responsible for the damage.  It appears that one of the cases in the center of your “collection” is a different species in the same family, a Household Casebearer Moth case, Phereoeca uterella, which according to BugGuide:  “feed on old spider webs; may also eat woolen goods of all kinds if the opportunity arises.”  BugGuide also notes:  “Larval cases can be found on wool rugs and wool carpets, hanging on curtains, or under buildings, hanging from subflooring, joists, sills and foundations; also found on exterior of buildings in shaded places, under farm sheds, under lawn furniture, on stored farm machinery, and on tree trunks.”

Many thanks really helpful
Regards,
Ashley

Citrus Swallowtail Caterpillar

Citrus Swallowtail Caterpillar

This is the Caterpillar of a Citrus Swallowtail, Papilio demodocus, a lovely butterfly that feeds on the leaves of citrus trees while in the larval stage.  All the features you describe are used as defense mechanisms by the caterpillar, which has a forked organ known as an osmeterium that is revealed and accompanied by a scent some predators might find off-putting.  We believe that is the thorn you have mentioned.  The eyes and mouth you mentioned are markings that might cause a predator, like a bird, to believe this is a much larger predator, like a snake, instead of a delectable morsel.

We were exploring a dark cave, in the marble mountains, near Hoi An, Vietnam, in March this year, and came across this spider. It’s hard to tell in the photo we took but it’s leg span was approx 5-6 inches. It had striped markings on it. It was in a pitch black cave, we discovered it trying to find our way using a camera flash! Would be really interested to find out what kind of spider it is!

Possibly Huntsman Spider

Possibly Huntsman Spider

Dear KH,
We cannot say for certain, but the general shape of this spider as well as the size you indicate leads us to believe this is a Huntsman Spider or Giant Crab Spider in the family Sparassidae.  We will attempt additional research.

Hi Daniel,
Thanks so much for getting back to me so quickly. That is really interesting, thank you!
Best wishes,
Kate

Hi,
I have been finding these little beetles on my windowsill in my atrium (18′ ceilings) and along the baseboards in that atrium. There is no carpet – it’ s laminate flooring. The house is only 7 years old. The atrium is our ‘dining room’ which is only used for dinner in the evenings and kept clean.
Can you please advise what the bug is – I’m assuming it’s some sort of beetle.

Varied Carpet Beetles

Varied Carpet Beetles

Hi Tammy,
You have Varied Carpet Beetles,
Anthrenus verbasci , currently our most common identification request with an average of five requests arriving daily.  Varied Carpet Beetles are members of the family Dermestidae, a group that contains many members that are cosmopolitan and that infest homes.  The adults, which you are finding, feed on pollen, and they are likely congregating on the window sills in an attempt to gain access to the outdoors.  The larvae are the pests that infest homes.  According to BugGuide, they are “primarily a household pest on plant (dried fruits/nuts) and animal materials; regularly encountered in dried-milk factories, occasionally in flour mills and warehouses” and they eat a “wide variety of materials of animal origin (wool, fur, skins…)(1); stored food materials and products (biscuits, cakes, seeds, wheat, maize, oats, rice, cayenne pepper, cacao, and dried cheese)”.  They are reviled in museums and BugGuide also notes they are: “arguably, world’s most important pest of insect collections.”  The best way to eliminate them from the home, in fact the only way to eliminate them from the home, is to identify the source of the infestation, the place where the larvae are feeding, and discard any food or other item that might be feeding the larvae.

I live in South Florida and I keep noticing these bugs inside of our apartment. It just started happening around February. They have wings although I’ve never seen them fly. We get sprayed by the exterminator in our apartment so I think I’m seeing them after they have been poisoned. They also have long back legs. Please help! I have an infant and a two year old this worries me. Thanks !

Ensign Wasp

Ensign Wasp

Dear Concerned Mom,
You should be concerned, but not because of this insect.  This is a beneficial Ensign Wasp, a species that lays eggs on the oothicae or egg cases of Cockroaches.  Developing Ensign Wasp larvae eat Cockroach Eggs and unhatched nymphs, helping to control the Cockroach population naturally, without the use of pesticides.  These dead Ensign Wasps are either the result of collateral damage due to spraying for Cockroaches, or they are the result of bug phobia.  Some folks believe any bug in the home is a problem, resulting in unnecessary spraying of potentially, environmentally toxic chemicals.  We believe that the use of pesticides in the home is much more harmful to infants and toddlers than an encounter with a beneficial Ensign Wasp which is not capable of stinging nor biting a human.

Thanks so much for your reply. When we first moved into our apartment we found out it was infested with cockroaches. They tried several different sprays and treatments finally the apartments pest control sprayed a bed bug spray that was extremely strong smelling all through the house. I don’t see cockroaches anymore except dead on occasion, but I see these often. Does it mean I still have a cockroach problem too? Is this something I should consider breaking my lease for because of my children? Thanks again for your reply.

Hi again Concerned Mom,
We do not want to provide any advice regarding relocation, but we can provide you with additional information that might help you make up your own mind.  There are several studies that link Cockroach infestations to asthma in humans.  According to the American Lung Association website:  “Cockroaches, those unpleasant and unsightly pests, are not just a problem to look at. They also produce substances, or allergens, that aggravate asthma and cause allergic reactions in people who are sensitive to those substances. The allergens produced by cockroaches are likely concentrated in their fecal matter and in fragments of their body parts. These tiny particles can become airborne and contaminate the air in your home.”  The site has much more information on the relationship between Cockroaches and asthma.  The pesticides versus the cockroach infestation seems like a choice between the lesser of two evils, and there are probably differing opinions on which is worse.  The Ensign Wasp continuing to manifest its appearance in your apartment is a good indication that the Cockroaches are still present, albeit unseen.

Oriental Cockroach

Oriental Cockroach

Though it is commonly called a Water Bug, this is an Oriental Cockroach, Blatta orientalis, and it is one of the species of pestiferous Cockroaches that is closely associated with human habitation.  They can become especially numerous in cool, damp places including basements and sewers.  According to BugGuide, they are:  “Omnivorous but prefers starchy or sugary foods. Often associated with garbage or decaying organic matter, indoors or out. Can survive one month without food as long as water is available, or two weeks with neither food nor water.”  Flushing it down the toilet, which is what it appears might happen immediately after this image was taken, will likely introduce it to more of its kin.
