Insect - Eriocampa ovata

Insect - Eriocampa ovata
Sitka County, Alaska, USA
July 21, 2008
I think this is a fly, but I'm not sure. It was neither particularly large nor small, perhaps 1 cm or less in length.

The behavior of this insect was interesting in that it did not seem inclined to fly away when I got close with the camera. Instead, when disturbed, it arched up into the position shown in this photo. I'm not sure if this was a way of emphasizing the prominent red patch, or something else.

ovata vs. ovatula
There's a vote for ovata and a vote for ovatula. Apparently we used to have a page for ovatula and it was renamed ovata. I moved to ovata. If there are two separate species on bugguide let me know what to create.

a sawfly (Hymenoptera: Tenthredinidae)
this may or may not be one of these 'slug' genera in the subfam. Heterarthrinae

Thanks
Seems like maybe it's the Alder Woolly Sawfly (Eriocampa ovata). The appearance is quite similar, it's known from Alaska (though introduced from Europe), and I saw more than one individual (including this one) on the alder trees where I took this photo.
