Caddisfly

Dear Confused new home owner,
You have no cause for concern.  Do you live near a body of water?  This is a Caddisfly.  Caddisflies have aquatic larvae that are known as Caseworms that are used as bait by many fishermen.

Your letter to the bugman:  I thought this was a cool image of a spider incapacitating a black swallowtail. This was along a trail, near the flowers the butterfly was feeding on. Maybe a crab spider? Enjoy!

Crab Spider eats Pipevine Swallowtail

Dear k. cassidy,
This is an awesome image.  We agree that this is a Crab Spider.  Crab Spiders do not build webs to snare prey.  Many species, especially pastel colored, pink, yellow or white Crab Spiders, are camouflaged in blossoms where they wait to ambush pollinating prey like bees and butterflies.  Your Swallowtail is actually a Pipevine Swallowtail.  Did you witness the Crab Spider capture the Pipevine Swallowtail?  If not, was the Swallowtail still alive when you encountered this awesome Food Chain illustration, though interestingly, this is not the first time we have received documentation of a Crab Spider eating a Pipevine Swallowtail.

Your letter to the bugman:  Dear bugman,
Found this small iridescent beetle in our garden and was able to catch the colors in this picture. With spring in full bloom, I’m excited to go out everyday to see what critters I find…

Rosemary Beetle

Dear T.M.,
We suspected this was a Leaf Beetle, and we located a very similar looking mating pair of
Chrysolina coerulans angelica on Israel’s Nature Site (scroll down) but your individual has many more alternating stripes on the elytra.  We searched the genus and we believe your individual is a Rosemary Leaf Beetle, Chrysolina americana, which we found on iNaturalist.

Your letter to the bugman:  Dear Mr. Bugman, it is fall and there are beautiful asteraceae flowering. I found this beautiful butterfly feeding on one Eupatorium inulifolium (I think) and would like your help with its identification please.

Diurnal Moth we believe

Dear Carolina,
We actually believe this is a diurnal Moth and not a butterfly, but we have not been able to locate any similar looking Brazilian specimens.  We need to do more research, and perhaps Cesar Crash or one of our other readers will recognize this beauty and write in with an identification.

Oh! Thanks for posting! Will standby for this moth ID.

Your letter to the bugman:  Hello! This large fly-like insect sat on our porch for several hours. I don’t know if it was injured, but it didn’t move much. I have been unable to match its photo. Thank you!

Male Robber Fly

Dear Ellen,
How nice to hear from you.  This is one of the predatory Robber Flies in the family Asilidae.  Because of the tufted abdomen, we are inclined to speculate that this is a male Robber Fly in the genus
Efferia, and though its markings are different, you can see that it resembles this individual on BugGuide.

Thank you so much! The photo in bug guide is amazingly detailed. Best wishes to you both.

Subject:  Borer Maybe?
Geographic location of the bug:  Los Angeles
Date: 04/15/2019

Your letter to the bugman:  Can anyone tell me what this bug is called and how to get rid of it? It’s super fast and skirts across branches to dodge you when you try to get a good look. It also sits on the tree and drips piss or something constantly so it looks like mist falling down. I’m pretty sure these things are killing a tree I planted recently.

Glassy-Winged Sharpshooter

Dear JV,
This is not a Borer.  This appears to be a Glassy-Winged Sharpshooter,
Homalodisca vitripennis, an invasive species that feeds by sucking fluids from plants.  Though large infestations might cause twigs to wilt or wither, there is a bigger threat of diseases spread by Sharpshooters.  According to BugGuide:  “A major vector of Pierce’s disease on grape. Usually not a serious pest within its native range, southeastern US. This species was accidentally introduced into so. California in the early 1990s, probably with ornamental or agricultural stock. There, it has become a serious threat to viticulture.”
