Predatory Stinkbug - Conquistator mucronatus

Predatory Stinkbug - Conquistator mucronatus
Pinellas County, Florida, USA

Is this a Florida P.S.? or maybe Anchor Stink Bug?
Prey is a zebra longwing cat.

I received a private email (I don't know why, maybe he saw this post on BG) from a guy (name withheld because I didn't ask his permission) from someone with this credential.

with photos of an individual captive raised and the photos were a spot on match.

Well done, Andrew!

Awesome! Thanks, mystery ID'er!
I'll have to look through the guide later to see if there are any other unidentified stink bug nymphs that look similar.

Neat one!
I relayed my thoughts to Vassili in e-mail, but I'll repeat them here too

This one has me stumped. I kind of wonder if it could be the nymph of Conquistator mucronatus though.

I looked through this paper a bit though


"Fifth-Instar Nymph (Fig 1E, 1F) Oval, convex, widest at third abdominal segment. Head shape consistent with fourth-instar nymph. Head color varying from red to black, base of head usually black. Eyes and ocelli red. Antennal segment I red to black depending on maturity, segment II gray to black, segments III and IV black, annuli white. Posterior portion of eye white in color and possibly lacking ommatidia (see eye pattern, Fig. 1E). Last rostral segment brown, remaining segments black. Thorax color variable black, red or orange. Legs typically with coxa, trochanter, and femur red, tibia, tarsi and tarsal claws black, annuli white. Legs all black if entire thorax black. Ventral pattern as in fourth-instar nymph. Dorsal pattern differing from previous stages. Scutellum and wing pads evident. Wing pads extending approximately to end of abdominal segment III. Lateral margins of thorax serrate, black and flat-tened dorso-ventrally."

I'd love to see an example of the individuals they mention that have the red thorax to see if there's some difference in the pronotum too. That seems to be the most obvious difference. The head color and rostrum description don't really match up, but it'd be worth looking at, at least.

Is it possible
this is a nymph of Vulsirea nigrorubra? That species only occurs in Florida (in Bugguide anyway)
Although I don't know if that species is predatory?

nice, intriguing one
Moved from ID Request.

Joe Eger says, "This is not any of the common species...
"...of predatory stink bugs. If I had to guess, I'd guess Podisus sagitta. Andy Santa Cruz has been rearing that species." (Joe will ask Andy to take a look. So, interesting find indeed --and nice shots!)

opinion of Andy Santa Cruz:
"Sorry I can't help. The bright red color may be transitory due to a recent molt. P. sagitta is similar to P. maculiventris if not paler. The unknown's markings lack white bands and more resemble A. grandis or E. floridanus but the shape is more Podisus. Perillus strigipes nymph comes close on the markings and shape but is typically much darker. I hope that he goes back again for another look."

to which Dr Egger added, "Maybe this thing is a Tylospilus. I doubt it is a callow nymph since it is feeding - mouthparts would need to be hardened."

Thanks for the feedback!
I have been looking for him but have been unable to find him again. I'll keep trying.
Thanks again.
Oh, BTW: Florida usually does have brighter and or more colorful individuals (as I'm sure you already know).
