Sawfly, larva - Haymatus blassus

Moved

Moved from Allantinae.

Paper published (see guide page)! I'm happy to send a PDF to anyone who wants it, although I haven't been able to download it just yet (inexplicable access issue with BioOne). This looks identical to Haymatus blassus, which is now confirmed as the species feeding on Philadelphus.

Me three

Would love to be included on that email once you manage to grab a PDF. Congrats on solving this mystery!

Dear Charley,

I would be very happy to receive this PDF.

I'd be interested...

...in seeing the paper, once you're able to download it.

Moved

Moved from Unidentified Sawfly Larvae.

probably Allantinae

(6 annulets) and it's most like some species of Allantinae than other subfamillies.

The stem...

...upon which the larva in this photo is crawling might be raspberry (Rubus): grooved, woody, red; there are thornless species.

Could it be Philadelphus?

This similar larva was found on mock orange, which has similar stems to this. (Thanks to Alexander Boldyrev for linking here from there).

i don't know how speciose the Rubus is here in NA but a friend [a botany professor from wUkraine] told me once that there are hundreds and hundreds of spp in the Caucasus & some other 'hot spots' --which i didn't believe till i saw some Carpathian samples in his herbarium -- also quite a variety of apparently stable, easily IDable forms [i'm not qualified to have an opinion of sp. concepts among plants]... i then started to pay att'n to the bramble in the wild and indeed found them surprisingly diverse... i look at their shoots ever since -- just for fun.

~225 species

...in North America (counting only full species, not subspecies, varieties, and hybrids), according to the PLANTS database.

not that sounds promising...

way to go! Bavaria alone has about 400, is i'm not mistaken

Possibly Red-headed Pine Sawfly, Neodiprion lecontei

I'm not an expert, but this looks like a Red-headed pine sawfly, Neodiprion lecontei, although the background colour is supposed to be yellow. One good feature is the red head. These sawflies are pests of pine plantations, but they do feed on other species.
