An Insect's approach to rearing your young
Using sight, sound and smell adult insects attract their mates and copulation can take place. The female then lays her fertilized eggs in an environment suitable for her larvae to exploit. Butterflies seek suitable plants for the young caterpillars, beetles lay eggs in pellets of buried dung, flies deposit eggs in carrion, wasps catch and paralyse spiders and lay their eggs on them so that the young larvae can feed on the spiders. Ichneumon wasps use a beetle grub to lay her eggs, with the hatched larvae eating the grub alive.
