NEW DESCRIPTIONS OF LARVAE OF FOREST INSECTS: NYCTOBIA, EUFIDONIA (LEPIDOPTERA, GEOMETRIDAE)

Abstract

Amongst the several species of greon loopers found on Canadian coniferous trees in July are two which, to the naked eye, appear somewhat similar. These are Nyctobia limitaria Wlk. and Eufidonia notataria Wlk. Larvae of these two, along with that of the other Nearctic species of Eufidonia, i.e. discospilata Wlk., a heath-plant feeder, are herewith described. The larva of E. notataria has been described briefly by Goodell (1, 2).
