Your letter to the bugman:  I have been bitten by something that has turned to serious outcome. These bugs were all over my marigolds and I got my hands in there and shook them out the same day I acquired a bite.  They returned the next day so I took a pic.

Goldenrod Soldier Beetle

Dear Jackie,
The angle of your image is not ideal for identification purposes, but we believe this is a Goldenrod Soldier Beetle.

OK.  There were also goldenrods but this bug was different from them.  I sure do appreciate you answering my inquiry.  It’s crazy but it’s a rarity that people do that anymore.  Thank you much.

Cecrops Eyed Silkmoth Caterpillar

Dear Urbanohno,
What a marvelous find.  These are caterpillars of the Cecrops Eyed Silkmoth which we identified on BugGuide.  According to BugGuide:  “Adults in spring. Eggs are laid in rings on twigs of host plant. Early instar larvae are gregarious and feed in large groups, but they spread out and become solitary in later instars. Larvae are present in summer to early autumn. Overwinter as pupae in cocoons woven among (or incorporating) vegetation, mostly leaf litter on ground, sometimes on plants.”

Ah so – Thank You very much Daniel!

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:  I was walking around Cahuita, Costa Rica the other day and found this lovely white bug. I think it’s part of the Mesquite family but I want to know which specifically as I cannot find any photos online with the same colour way or patterns. Thanks

True Bug Nymph:  Ouranion species

Dear J,
This is a True Bug nymph and it might be a relative of a Giant Mesquite Bug.  We have several images of this nymph, also from Costa Rica, that were submitted to our site in 2015 that we never conclusively identified.  At that time we speculated they were in the genus
Thasus like the Giant Mesquite Bug.

Hi Daniel!
Thanks for getting back. I have read that post too and my partner also thinks the same but I guess he wasn’t sure or knew it was a nymph. Thanks again!
Kind regards,

Update:  Possibly Ouranion species.
Thanks to Cesar Crash of Insetologia who sent a comment that this appears to be a member of the genus
Ouranion.  According to iNaturalist, Ouranion and Thasus are in the same tribe Nematopodini.
