Sawfly on Philadelphus coronarius

Sawfly on Philadelphus coronarius
Adairsville, Bartow County, Georgia, USA
April 15, 2015
Believed to be the adult of the larvae that decimate my Philadelphus coronarius every spring. Eat the shrub down to sticks - shrub then refoliates and next year the process begins again. Images are not the best due to old digital camera and this fly's inability to be still for more than a nanosecond. Lots of wing snapping/fluttering and near hyperactive movements. Have photos of larvae as well and an odd adult.

Moved from ID Request.

Thanks--parking all these photos in Tenthredinidae for the time being.

We have a bit of an organizational issue here...
Linking is reserved for different views of the same individual or group of individuals (for "group" think aphid colony, anthill, bee swarm, etc.). Here we have linked together multiple adults, larvae and eggs that may or may not bear any relation to one another. The larvae can probably stay linked together, if they were all feeding in close proximity (though we probably don't need all of them). The adults and the eggs will need to be unlinked and posted separately, however. The different stages can be cross referenced by placing thumbnails in the Remarks section of each, if you like. If you need assistance with any of this, please let me know.


Hi Ken,
Sorry for the mess - I hope I've gotten/am getting it sorted. Will try to link what needs it and unlink the rest. Removed some repetitive shots as well. If you have any more suggestions, please let me know. I was a bit enthusiastic.

No problem :)
Thanks for the quick response. It looks as though everything has been unlinked, relinked and cross referenced appropriately. I'll be eager to learn what Dave Smith has to say.

Since you unlinked them,
please add the other thumbnail images in so they can be found easily--I don't have time to do it right now, but I want Dave Smith to be able to see them. I showed him these photos last night and he said:

"I wish you had gotten a specimen, but I’m almost sure this is a species I described, Haymatus bassus. It fits the female description perfectly. I won’t be back to the museum until next week and will compare the pictures with specimens then. A very rare thing. The only specimens I’ve ever seen are the 3 males for the original description and the two females in the attached paper. If this is right, another great host record! Will check back with you when I examine the specimens."

Hi Charlie,
I'm working on getting the thumbnails done. Please let me know if there's more that you'd like to see. I'm not completely familiar with how the images and links and thumbnails work, so if there's one you want somewhere/doesn't show where you'd like/etc, give me a shout and I'll work on it. Thank you for the comment, too, and showing these to Dave Smith! I'm really excited about the possible i.d.
