I've seen these in spring before. These are on ash tree leaves, but I've also seen them on black cherry tree leaves. Any ideas what they are?

These are larvae of sawflies (Hymenoptera: Tenthredinidae); likely either the blackheaded ash sawfly (Tethida barda) or the brownheaded ash sawfly (Tomostethus multicinctus) - see http://tinyurl.com/cru5el [note that Tomostethus is misspelled "Tomostehus"].

They're all over my Texas Ash and no sign of them going away. I'm picking them off the best I can. Oddly enough, they were on an Arizona Ash (which I don't even like) first, but now just my Texas Ash, which I really love! I think it's one of those two...so thanks!
