Not a great shot as the sun caused some problems. May be enough for some ID which would be appreciated.

Moved from Onycholyda.

This is Onycholyta sitkensis
This is Onycholyta sitkensis (Kincaid). A western species that feeds on Rubus.

As a note
Catalog of Hymenoptera in America North of Mexico lists three species of Onycholyda which are found in B.C.
O. excavatus, O. multisignatus, & O. excavatus.

O. excavatus is a parasite of species, O. excavatus of Rubus. it is not notes what the host of O. multisignatus is.

Not much help but it narrows down the field a little.

Onycholyda cf. luteicornis

Sawfly, but may not be Pamphiliidae.
Many of the Tenthredinidae are also ornately-marked. Pamphiliids tend to have large, ROUND heads, and more robust bodies. This one looks to have a more squarish head, which has me leaning heavily toward Tenthredinidae. The antennae on this specimen DO suggest pamphiliids, but that could be an artifact of motion blur, too.

Added a couple of poor images that may help. Bought your book Eric at a nature center.

 
Thanks on both counts!
I stand corrected. It IS a pamphiliid. I can now clearly see the many, diminutive antennal segments, in contrast to the much longer antennal segments of tenthrenidiids. Thank you for the additional photos; and thanks for the book sale:-)

 
Thank you Eric, glad the othe
Thank you Eric, glad the other images helped, although they were rather poor. I like the book. If you have a little free time have a look at our new nature site. My photos, sons technical stuff. All subjects. http://www.dereilanatureinn.ca/

I agree; looks like a Pamphilliid
Are there a good number of these sawflies in this location? They can be very rare overall, but locally abundant. If there are, I am interested in these for my research with Hymenopteran ovipositor morphology. Please contact me Andy.Boring@uky.edu if you would be able to collect more of these. Thank you.

My only other image posted of a sawfly was Photo#100355 posted March the 29th. I did take three other shots of the one on this page you commented on, but they weren't very good, just a record I guess.

I basically take all these insects etc. that I have submitted in our garden, out of the 2 hundred or so that I have had ID.d, this is the first I have seen and a first time image other than an early stage shot taken last year. I try each day to add images if the weather permits.

 
I was a bit more interested i
I was a bit more interested in the specimens themselves - dissecting them for morphological studies. I understand that they are fairly rare so you are pretty lucky to get to see them alive.

looks like something in the family Pamphiliidae... that is the best i can do.

Thank you Edward for your reply, much appreciated.
