Your letter to the bugman :  I am an undergraduate at the University of New Mexico and I am currently working in a lab that studies ecological relationships. I am very interested in beetles and I am hoping to do research on them for my master’s. While out doing field work I came across this beautiful guy, I was able to determine that it belongs in the genus Lytta, but I am unable to identify a species. Any insight would be helpful and much appreciated!

Unidentified Blister Beetle

Dear Emily,
Blister Beetles are indeed fascinating.  This does appear to be a member of the genus Lytta, and it resembles the Master Blister Beetle, though it is lacking the red thorax.  The closest match we could find on BugGuide is the Red Eared Blister Beetle,
Lytta auriculata, but we are not convinced that is your species.  Your individual appears to have short, textured, green elytra.

Update:  July 20, 2021
Frequent contributor Cesar Crash from Insetologia believe this might be Eupompha fissiceps which is represented on BugGuide.

I was able to ID this guy as Eupompha fissiceps

Your letter to the bugman:  Dear Bugman, While out birding in the disc golf course behind my house, this bug landed at my feet. It is about 1.5 inches as I recall. The furry legs caught my eye. I can find nothing on the internet that resembles it. The area is high desert with sage brush and juniper. I took this picture on June 26. Thanks.

Unidentified Robber Fly

Dear J. Shipman,
This magnificent predator is a Robber Fly in the family Asilidae and we believe it is in the subfamily Asilinae.  There are numerous similar looking individuals on BugGuide.

Hey, thank you so much, and for such a prompt answer! I Checked out BugGuide, as you suggested, and also found a lot of info about Robber Flies on Wikipedia. Gosh, what a brute! Are they found only in the West? I’m originally from the East Coast, and I’ve never heard of these guys. Cheers – J

Your letter to the bugman:  Hey Bugman, spotted this Little critter tonight. Is it a moth? If so, what kind? I’v had a search online but can’t find anything similar.

Geometrid Moth

Dear LJ,
This is a moth not a butterfly, and it is in the family Geometridae.  There are many similar looking species and we did a quick search on Butterfly House and could not quickly provide you with a species.  We hope a family identification is sufficient for your needs.

Your letter to the bugman:  My friend took this pic and because she knows my love of all things “bug” asked if I could find out anything about it.  Been doing some poking around and the  closest I could find was family Ichneunonidae Megarhyssa nortoni.  It’s quite striking in coloration.  Just wanted to share because I haven’t found a photo anywhere that matches

Parasitic Wasp

Dear Terriann,
This is definitely a member of the superfamily Ichneumonoidea that includes the family Braconidae as well as the Ichneumon, and we believe this might be a Braconid, possibly in the genus
Atanycolus that is represented on BugGuide.  A definitive identification might not be possible as this is a huge superfamily with many unidentified members.  According to BugGuide:  “Next to impossible to identify this genus from images alone, however it is one of the more common genera in the subfamily. Identification of images on this guide page are NOT absolute! “

Your letter to the bugman:  Hi Bugman,
Guess I’ll need to be extra careful when watering the plants in my back yard.  Can you identify what will emerge from this chrysalis?

Probably Brush Footed Butterfly Chrysalis

Hi Jeff,
This is definitely a butterfly chrysalis, and we are pretty certain it is a Brush-Footed Butterfly in the family Nymphalidae, but we have not had luck with a definitive identification.  This is a rather distinctive chrysalis and we don’t know why the identification is giving us trouble.  We will attempt to contact Keith Wolfe for assistance.

Probably Brush Footed Butterfly Chrysalis

Thanks Bugman,
At first I thought it might be a Gulf Fritillary, but the small “threads” protruding at the end ruled that out. Haven’t seen a Brush-Footed Butterfly in my back yard before, so I’m hoping to be there for the emergence.

Your letter to the bugman:  Good day,
Please can you ID these two spiders. The large one is beautiful. They were on a dead tree stump in the dam. The large one was walking down the stump under the water and coming back up, perhaps looking for food?

Fishing Spider we believe

Dear Jacqui,
The behavior you witnessed, “large one was walking down the stump under the water and coming back up, perhaps looking for food?”, and the markings on the carapace are both consistent with Fishing Spiders from the genus
Dolomedes found in North America, as evidenced by this BugGuide image.  While we have not had any luck locating any similar looking South African members of the genus, according to Wikipedia:  “The second largest number of species occur in tropical Africa.”  Perhaps one of our readers will be able to identify your gorgeous spider to the species level.  We do not know the identity of the smaller Spider in your image.  According to Science Direct:  “Sierwald (1988) examined predatory behavior of the African pisaurid Nilus curtus O.P.-Cambridge (=Thalassius spinosissimus [Karsch]). Its hunting posture is like that of Dolomedes, anchored by one or more hindlegs to an emergent object with its remaining legs spread on surface of water. When disturbed, the spider pulls itself below the surface of the water by crawling down an emergent object. They can remain submerged for up to 35 min. Prey swimming under water (insects, tadpoles) are grabbed by the front legs pushing down through the surface film. Prey trapped by surface tension were jumped on if close enough, or rowed to if further away.”  Members from the genus Nilus pictured on iNaturalist do resemble your individual.
