Black-headed ash sawfly larvae? - Tethida barda

Moved

Moved from Frass. Cropped it down so the thumbnail shows the larvae better.

Frassed

Moved from Black-headed Ash Sawfly. Plant IDed, bug IDed, plant image no longer needed.

Dorsal view

I actually included this image in the series because it was my only dorsal view of the larvae, not because of the plant leaf. If you think it should be frassed, that works for me.

Single-leaf Ash?

Although the larvae resemble ash sawflies, this did not look like an ash leaflet to me (small, oval, winged petiole) and none of the four ashes native to Oklahoma (Fraxinus americana, F. pennsylvanica, F. quadrangulata, and F. texenis) look like this. However, noting that it was growing on the grounds of a zoo, I broadened my search to any ash documented from North America using the USDA PLANTS database. Lo and behold, there was one species with anomolous leaves, appropriately named Fraxinus anomala with the common name of Single-leaf Ash. Its leaves do look a lot like yours. It is a small tree or shrub whose native range is the southwestern U.S. Check to see if the rest of your plant's characteristics match up with this species; maybe your horticulturalist would know.

Thanks to both Johns.

I have several plants to get identified, so I will check with the hort staff to see if I can put names on all of them.

Plant IDs

We have a page for plant identifications related to insect identifications: http://bugguide.net/node/view/487026/bgimage.

I wasn't aware of this page, sorry.

I didn't gather much of the plant in the image, unfortunately. We have a hort staff on-grounds but I was on my lunch break and didn't have time to ask anyone for a plant ID. I need one of them to follow me around during this time of year so I can get better details for my spottings.
