Description

The egg size, fecundity, and larval head width of 5 polyphagous Amphipyra species, A.livida, A.monolitha, A.tripartita, A.schrenckii and A.erebina were examined. There were no relation between the egg size and the forewing length. The fecundity also showed no special relation to the forewing length. However, there was clear tendency that the egg size was changed in an inverse proportion to the fecundity. The gradient of head growth line showed a parallel change with the egg size and fecundity. The monophagous species A.subrigua, additionally reared, had a somewhat specialized head growth pattern with a lower gradient of growth line than the others. Possible implication of the results were discussed.
