Here are four dragonfly nymphs (or larvae if you prefer) that I dug up yesterday at Ice House Lake,
Washington. The big spiny one at upper left is a Spiny Baskettail (Epitheca spinigera), the little guy
below that is a young Common Whitetail (Plathemis lydia); going right, the big dark one near the
middle is a Libellula (probably Eight-spotted Skimmer, L. forensis); and the little one at far right is
either a meadowhawk (Sympetrum) or a whiteface (Leucorrhinia)—I didn’t keep track of which
nymph was photographed here and I can’t tell which it is from the photo.
