This bug bit me get I see no pincers or stingers. It has long antenna, long skinny wings, a short body and is greyish in color.

Dear Anne Marie,
This looks to us like a Caddisfly in the order Trichoptera, and we would challenge your belief that it stung or bit you.  Most Caddisflies do not have functional mouthparts, and they do not feed as adults.  According to BugGuide:  “Some adults take liquid food, such as nectar, others do not feed.”  They do not possess stingers either.  Is it possible that you have mistaken this Caddisfly for the creature that bit you?

I know that this is a caddisfly, any idea what genus or even species? Do you have any good resources that are user friendly in regards to identifying caddisflies?

Dear Gary,
This is a marvelous image of a mothlike Caddisfly, but we don’t know its species, we find the identification of Caddisflies to the species level to be something outside of the range of our present abilities, and we don’t know a Trichopterist.  We will do a quick look on BugGuide to see if anything jumps out at us.  Both this similar looking individual on BugGuide and this similar looking individual on BugGuide are only identified to the order Trichoptera.

Hi bug people!
I love your site, just stumbled on to it trying to get info in phoretic mites on a Holoptera beetle I found yesterday.
While perusing your site, I noticed several partially IDed caddisflies and the statement that you don’t currently know a trichopterist.  Well, I don’t lay claim to the title trichoperist these days, but I’ve spent many years studying them, have many identification resources on hand, and still quite a bit of personal memory about many caddisflies.  I’m also still personally connected to and correspond with many of the the few working trichoperists in the US.  I also co-authored a checklist of caddisflies of Tennessee several years ago (Etnier, D.A., J.T. Baxter, S.J. Fraley, and C.R. Parker. 1998. A checklist of the caddisflies of Tennessee. Journal of the Tennessee Academy of Science 73:53–72.).  I’m currently a working aquatic biologist focussed mainly on the conservation and restoration of native fishes, mussels, and crayfishes, but continue to pay attention to bugs, if not study them any more.
The upshot is I’d be glad to take a whack at IDing caddisflies for folks, if you still need some help.
Best to you,
Steve

What’s this bug? Can’t tell from the picture, but it has 3 white lines on it’s wings. The picture was taken, 1/9/14 which is winter for us in the Pacific Northwest.

Dear Elizabeth,
This is a Northern Caddisfly or Snow Sedge.  Caddisflies are often mistaken for moths, and according to BugGuide:  “Adults resemble moths, but wings are hairy instead of scaly.”  Caddisflies also share some behavioral characteristics with moths.  According to BugGuide:  “flight activity begins at dusk. Adults are attracted – sometimes in great numbers – to artificial light.”  Larvae, which are commonly called Caseworms, are aquatic, and of the habitat, BugGuide notes:  “Species most diverse in well-aerated streams, but also occur in lakes, ponds, and marshes.”

Thank you so much, Daniel Marlos!!

Hello!
I found this bug near the Sauk River in Washington State. If you are able to identify it, I’d be very happy.

Hi Darcy,
We hope an insect order will suffice.  This is a Caddisfly in the order Trichoptera.  According to BugGuide, there are:  “>1,350 spp. in ~150 genera of 22 families in NA” and we haven’t the necessary skills to provide a more specific taxonomy than the order.  Caddisflies are feeble fliers and they are often confused with moths.  Because they cannot fly great distances, they are generally found not far from water where the aquatic larvae develop.  Caddisfly larvae often build distinctive shelters from pebbles, shells, twigs and other aquatic detritus, and for that reason they are frequently called Casemakers or Caseworms.  Freshwater anglers use Caddisfly larvae as bait.

I actually found this bug inside our home. I thought it was a piece of plastic that came off of our grocery’s that we brought home. It looked shiny. I thought it was a sliver of plastic until I scooped it up and it moved in my closed hand. I kinda screamed and dropped it fast. Mind you I am a 50 year old Tlingit woman who was born and raised in Alaska. My husband calls me an ”urban indian.”
After I washed my hands in both the kitchen and bathroom sink, I composed myself and decided to rescue the insect by trapping it with a mason jar and piece of paper. It crawled on the paper and I put the mason jar over it and took it outside. I placed it on the wood deck and watched it for a long time. It only crawled around and stood still for most of the time.
It is about 2 inches long.
It has black beady eyes.
Long antennae’s.
Long skinny shiny brown and white spotted wings that hug its body at the side.
I’ve seen the wing colors in all various shades of brown and even orange. Like fish egg orange.
Sometimes spotted and not. Their wings look shiny too.
I’ve seen them with their legs and wings tucked in, so they look ultra skinny, hard to spot.
I think they like to hang around the Alaskan wet woods.
I’ve occasionally seen them and wondered what kind of bug is it.
My twin sister in Juneau said they never see that kind there.
Thank you very much!

Dear Scared of insects, but fascinated with them,
We hope our response will prompt additional curiosity and not fear and loathing.  This is a Northern Caddisfly and previous research unearthed the common name Snow Sedge.  Please see our previous posting on the Snow Sedge for more information and links to our research.  Caddisflies cannot survive in polluted waters, so their presence is an indication of the purity of your local streams and ponds.

I was wondering if you could tell me what this brown flying insect is, as seen in a Pacific Northwest living room on 01/31/2013. I’ve never seen one of these before, and now this is the second one I’ve found inside a house in two days. It may be very common, but is new to me. It’s brown and about 1 1/2” long. The pattern on the wings makes it look like it is made of wood. I thought it was a moth when it first flew by, but it is sort of slow moving, a clumsy flier, and heavier. Any thoughts?

Dear A.,
You have had an encounter with a Caddisfly in the order Trichoptera, and as we learned from BugGuide, there are:  “1,350 spp. in ~150 genera of 22 families in NA [North America]“
and we cannot say for certain how to classify it more specifically, though it does closely resemble several photos from the genus Psychoglypha that can be found on BugGuide.  Like you own observations, BugGuide notes that “Adults resemble moths, but wings are hairy instead of scaly.”  Larval Caddisflies are aquatic and they construct shelters, so they are commonly called Caseworms.  Interestingly, each species of Caddisfly Larva builds a different shelter, some of sticks, some of stones, some of shells and others from other materials.  According to bugGuide:  “Most species live in a mobile case constructed from plant material, algae, grains of sand, pieces of snail shells, or entirely of silk. The case is held together with strands of silk secreted by the larva. In some species the case is attached to a rock, log, or other underwater surface; a few species have no case and are free-living.  The case’s particular shape and construction material is distinctive of the family and/or genus, and can be used in identification. Example: Helicopyschidae larvae use sand grains to build spiral cases that resemble small snail shells.”

You are amazing! Thanks so much for the response. Mystery solved.
