Caterpillar - Nematus ribesii

Caterpillar - Nematus ribesii
Cochrane, Alberta, Canada
July 3, 2007


Excuse me
but this is Nematus ribesii , prepupa.
After the last molt, the larva loses black spots, but the yellow rings on the thoracic and 8th abdominal segments remain.

here is the moment of molting:

and just a photo:


Tenthredinidae, Nematinae
Pristiphora appendiculata (Hartig). A rather common sawfly on currant and distinguished from the other currant-feeding species, Nematus ribesii by lacking black spots on the body. Widespread in North America, and probably an introduction from Europe long ago.

Moved from ID Request.

Lots of legs...
Hi Willy, I just read about sawfly larvae. I learned that they have more legs than other caterpillar-like creatures. In your photo I see three larger legs in the thorax/chest position, then many smaller legs, perhaps six more. And each leg we see on this side would have an opposite that we cannot see. So that's about 9 pairs of legs. And I have enough trouble managing just the two...

Sawfly Larva
It is definitely a Sawfly Larva and I would sure like to know which one. All I know for sure is, that it is not 'Nematus ribesii' even though it was found on a Currant bush.
I'm with you on the Legs part, I'm having problems with mine too, specially after a few Scotch's

Looks to be a sawfly larva instead
Do you know the plant it is on?
