Nematus vent*ralis? - Nematus iridescens

Nematus vent*ralis? - Nematus iridescens
VANCOUVER, Lower Mainland, British Columbia, Canada
September 30, 2012

Moved from Common Sawflies.

Tenthredinidae, Nematinae
Probably Nematus iridescens Cresson. Nematus ventralis is an eastern species. Nematus iridescens larvae are very similar to N. ventralis, but it is a Pacific coast species. Both feed on willow. The adults are different, but I hesitate to put a name on larvae since I can't tell the two apart.

Moved from ID Request.
