Hello all Here are 4 pictures of a insect from the Phyllophaga genus. Do you think it is possible to identify its species? Thank you very much for your help... Michel (Pictures took in Quebec (near Vermont) last May 2nd, 2010).     |

Greetings,
It's not possible to determine this to species with any certainty without dissecting the genitalia, but the most common species in your area should be P. anxia, although P. fusca and P. drakei should be there as well and they are nearly identical externally. Doesn't appear to be any of the other species likely in your area - several like P. longispina, P. hirticula and P. vilifrons all have noticeable hairs on the upper surface; P. futilis tends to be more orangish and has odd boot-shaped hind spurs in the male; and P. marginalis and P. rugosa have heavily punctate pronota. Further, P. drakei tends to be a summer species, so I would say it is possibly anxia or fusca, both of which are earlier spring species...
Cheers!

Hello Bandrow,
Thank you very much for your very interesting and pertinent answer! It is really appreciated...
Even that I take note of the possibility of P. fusca or P. anxia, I will stay with Phyllophaga sp.
But I keep preciously the info you gave me!
Cheers,
Michel

Hi Michel,
That is always the safest thing to do - stay with "sp." until it can be determined to species without doubt.
Cheers!
