       Although a single species Ochrogaster lunifer has been indentified, differences in
       nesting habits and behavior indicate that there are at least
two species.

Larvae of  Callosamia promethea.  Prelimary observations indicate that the early instars desposit and follow trails that facilitate aggregation.

Two North American species of social caterpillars whose larvae lay down and follow trails that serve to keep the caterpillars together as they move about the host. (Left) larvae of the brown trail moth, Euproctis chrysorrhoea (Lymantriidae). (Right) Hemileuca maia (Saturniidae), the larvae of which are processionaries. small caterpillars
