have "lips" hinged in two places with grasping
pincers on the end for catching prey. Brown and green bodies tend to provide
camouflage and allow the nymph to blend in with the habitat of plants and
pond bottoms. Gills inside the abdomen get the oxygen from the surrounding
water. Water drawn into the
nd through the gills is expelledto push the nymph through the water.
Dragonfly nymphs require 4 to 8 ppm of dissolved oxygen to survive.. They have
three segmented legs. You can distinguish a dragonfly nymph from a damselfly
from the round to oval shape of the body that ends in wedge shaped tails. It is
also helpful to use a diagram to identify the nymph.
