Suggestions for photographing larva of Lepidoptera

Most Plusiines cannot be reliably IDed from a larval photo.

Detailed information regarding difficulty of identifying Plusiine Family larvae in "Owlet Caterpillars of Eastern North America" by David L. Wagner, et al. -- pp 291-293 in PDF version of text (without photos)

  • Owlet_Caterpillars_of_Eastern_North_America_Lepido.pdf

Note for Geometer larvae

  • Geometer moths may be easiest to identify in the larval stage, thanks to their unusual appearance. The caterpillars bear just two or three pairs of prolegs near their hind ends, instead of the five pairs found in most butterfly or moth larvae.

Lepidoptera Biodiversity

Micros through Tortricidae

Plusiinae caterpillars can be identified by their common body characteristics - all have reduced prolegs (typically only three pairs rather than the usual five, though one genera has four pairs) with a gap before the rear prolegs.
