This picture shows several early instar nymphs in three different stages on an egg mass: the one dark red nymph is a first stage or instar nymph, the light red nymph has just molted and is therefore a new second stage or second instar nymph. The other 4 black nymphs are second stage or second instar nymphs. It is at this stage when aggregating nymphs may have a tick-like appearance. Note also that all the eggs have hatched.
