Slender Winter Stonefly (Capniidae)

Slender Winter Stonefly (Capniidae)
Fleetwood Creek, Central Ontario, Ontario, Canada
April 13, 2008
Size: 1cm
Can anyone identify this Slender winter stonefly to genus?

Moved
Moved from Green Stoneflies.

Capniidae, teneral
Matthew had the family right; viewing the wing venation in the full size version shows it to be a capniid, probably Paracapnia. The yellow coloration is due to its teneral condition, as Eric supposed.

Moved
Moved from Stoneflies.

Chloroperlidae, i believe
*

Not sure.
Not sure you even have the right family. This specimen 'looks' teneral, meaning pigments are not yet fully expressed.

 
Keys out to Capniidae,
The second tarsal segment is shorter than the first and/or last segments, as well the first segment of the tarsus is as least as long as the last segment. You'll find a strikingly similar image in Steve Marshalls "Insects: Their Natural History and Diversity" on page 55.
