Your letter to the bugman :  I have seen several of these in my house, at night. I see them flying and land on walls or they drop down to the floor or counter. When on the wall they tend to just stay there moving their head around almost as if looking at me. Sometimes they’ll have their backs arched looking behind them while standing still on the wall.

Your letter to the bugman:  Could you please identify this insect. I found a few (~5) in my house over a few days this summer at night around my lights. They are 1/4-3/8 inch long

Dear Sfigurac,
This is a benign Webspinner, and sometimes winged males are attracted to lights in great numbers.

Thank you very much for the quick response.
Your information has been very informative and helpful.
Your website seems like an excellent resource which I definitely share with others.

Your letter to the bugman:  For the last several days a few of these bugs have been showing up inside our house. This evening, a huge group was swarming every light we had on. Can you tell me what this is? We have screens on all of our windows, so I’m concerned about how they are getting in. Appreciate your help if you can share any info. Thanks!

Dear Amy,
This is a benign Webspinner in the insect order Embiidina, and you have already discovered what BugGuide remarks:  “winged males of some species come to lights.”  BugGuide also notes:  “rapid runners, often run backwards; live in colonies (in galleries of spun silk) and exhibit limited maternal care for eggs and young.”  We don’t provide extermination advice, but you can try dimming the lights, keeping lamps away from windows and checking the screens for access points.

Your letter to the bugman:  Hi Bugman,
My friend has these at her house. Is this a termite?

Dear Prisha,
Though it resembles a winged Termite alate, this is actually a benign Webspinner in the order Embiidina.  We had one reader submit a Webspinner Dynasty inquiry after she allowed them to cohabitate in her bathroom.

Your letter to the bugman:  I found two of these in my kitchen, and can’t find a match anywhere. The closest i found was a snakefly larva, but it didn’t match completely

Dear Dave,
These are benign Webspinners in the insect order Embiidina, and according to BugGuide:  “slender, usually brownish insects that may have wings (males) or be wingless (some males and all females); body of male flattened; body of female and immature more cylindrical; tarsi 3-segmented; basal segment of front tarsus greatly enlarged for producing silk from hollow hairs issuing on the basal and middle segments; cerci 2-segmented (but left cercus of some males 1-segmented).”  You might enjoy our Webspinner Dynasty posting.

There’s a bug that likes to come through my screens at night – mostly in the monsoon/late summer/early fall season. They like light and seem to be harmless and they have landed on me before with no problems.  They are usually only one or max two that are inside at any given time. They are pretty small. I would say somewhere between a small black ant and small earwig size. They fly and have translucent/white wings that lie flat, folded over one another the length of their body.  The length of the wings seems to line right up with the end of their bodies.  They have little “things” coming off their ends that someone told me meant they were earwigs.  I have seen flying earwigs before and the earwigs we have here don’t look like this guy.  They don’t behave, look or smell the same at all (these guys don’t smell and I think earwigs stink).

Dear Buggy-Bug-Bug,
This looks to us like a Webspinner in the insect order Embiidina based on this BugGuide image.  According to BugGuide:  “rapid runners, often run backwards; live in colonies (in galleries of spun silk) and exhibit limited maternal care for eggs and young; winged males of some species come to lights.”
