Yellow caterpillar with black spots

Yellow caterpillar with black spots

Moved

Tenthredinidae
Nematinae, belongs in Cladiini. Possibly Trichiocampus viminalis but pattern does not quite fit.

Moved
Moved from ID Request. A sawfly expert has recently begun frequenting BugGuide. He is most likely to see your image here.

looks like a Sawfly larva

yellow caterpillar black spots
last week one of these fell on my trousers.
had quite a time to observe and take pictures.
it definitely is a caterpillar in my opinion.
i live in the Netherlands, the caterpillar lives next to a lake called Slotermeer in Friesland

 
Sawfly larva
Given that a sawfly specialist (Dave Smith) has already identified the tribe of sawflies to which this larva belongs, I'm afraid your opinion that it "definitely is a caterpillar" doesn't carry a lot of weight. The larva you found in the Netherlands, of course, may or may not be related to this one.

 
sawfly or caterpillar
I apologize for being so wiseguysish on this subject.
Yesterday I learned that it definitely is a sawfly larve.

 
Definitely a sawfly larva,
there are very few with such long hairs. and most are in Cladiini. If my assumption that this may be T. viminialis (which feeds on pooplar) is correct, it also is found in Europe. I'm being a little cautious about its id.

 
Sawfly larvae
Thanks! Didn't realize it wasn't a caterpillar. Any idea what this one eats?

 
Thanks Peggy
Thank you Peggy for posting my picture....I have a lot of these by my house. I think it's either a Pine sawfly or Dusty Birch larvae, but I can't tell for sure. These seem much brighter in color than the ones I have seen in other pics.
