Question

A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oak twigs. The biologist caught many female moths from the same population and collected their eggs, putting at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below. Environment Temperature (°C) Day Length (hours of sunlight)

Answer 1

3.) Looking like their food source lets the caterpillars blend into there surrounding, reducing predation.

It's very hard for the predators to locate prey from the same back ground as compare to the contrasting background.

This property is called camouflage, which serves as a selective advantage for the survival of a species.
