Fishfly Pupa - Chauliodes pectinicornis

Fishfly Pupa - Chauliodes pectinicornis
Ellerbee Creek headwaters, Durham County, North Carolina, USA
July 7, 2005
Size: circa 30 mm
Found under a rock in a drying puddle in some woodlands by Josh Rose. Size estimated. Appears to be the pupa of Chauliodes pectinicornis, a common species in this area--see comments.

Pupa, not larva.
This is actually a pupa. Many neuropterans have very active pupal stages.

Neat, compare adult
Oh yes, I see, one can even see what look like the adult markings on the pronotum. Compare Chauliodes pectinicornis:

I see the little curlicue marks of the adult through the pupal skin. These marks are diagnostic for that species, as opposed to the similar C. rastricornis. The former is a common species in our area, and the phenology looks correct, if this thing was about to emerge--C. pectinicornis flies in July. So I'll be bold and move it.

If I had known this was a pupa, I would have brought it home to watch the emergence.
