Eggs are laid at twodistinct times of the year: early in spring when the oak trees are flowering and in midsummerwhen flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and looklike oak flowers, but caterpillars that hatch in summer feed on oak leaves and look like oaktwigs.How does the same population of moths produce such different-looking caterpillars on the sametrees? To answer this question, the biologist caught many female moths from the samepopulation and collected their eggs. He put at least one egg from each female into eight identicalcups. The eggs hatched, and at least two larvae from each female were maintained in one of thefour temperature and light conditions listed below.TemperatureDay LengthSpringlikeSpringlikeSpringlikeSummerlikeSummerlikespringlikeSummerlikesummerlikeIn each of the four environments, one of the caterpillars was fed oak flowers, the other oakleaves.
