No Taxon - Scymninae Larva (Lady Beetle Larva) - imm.
Size: approx. 5-10 mm. Photo: 09/20/11, 11 am.

The larvae of certain lady beetles (those in the subfamily Scymninae) are covered with white wax that can form long "hairy" tufts. The identification of the larvae is very difficult unless one captures them and waits.
