Cordulegaster maculata nymphs - three year classes. - Cordulegaster maculata
Town of Marathon, Shack Creek, Thunder Bay District, Ontario, Canada
July 8, 2010
Size: various
It take three or four years for nymphs to mature - here are three cohorts.

Indeed!
It is also great to realize how much the younger cohorts resemble the larvae of other groups. Very neat series!

Nice!
Excellent to see these in a single image.
