Observations and comments

At least some species are gregarious. When they change instars the gregarious species will come down out of the canopy and rest on tree trunks in dense aggregations composed of hundreds of individuals. It is in these aggregations that parasitoids were observed attacking the caterpillars. If sudden high pitched noises are made near the aggregation the entire mass will eventually respond with co-ordinated head flipping. Occasionally some individuals in the groups will also wriggle for an extended period. These caterpillars are often encountered on trails and buildings dispersing either to a new host plant or to pupate. The caterpillars have a powerful sting, frequently making chance encounters an unhappy occasion.
