The conspicuous body colouring of certain nocturnal invertebrates, such as the white forehead stripes on the brown huntsman spider, lures the flying moth to its predator. The larvae exhibit variable color patterns, though mostly yellow or white hairy bodies are the most common forms (Photo 2).

Their caterpillars are brown in colour, have a large black band with white dots. Only the males are capable of flight. One summertime control strategy aimed at limiting the damage the moths do takes advantage of that behavior. The total number of egg masses they find helps them predict whether defoliation of more than 50 percent of the forest canopy is likely. [14], It takes around 27 days for D. elpenor to move from the larva stage to the pupa stage. She deposits the tan-colored structure that can contain up to 800 eggs on a tree trunk, fence post or other solid surface.

Most Grevillea varieties are very fast-growing, tough, and low maintenance. It is outlined by white fringes. [21], Some natural predators use bright colouring to attract its prey, which includes D. elpenor. Large irregular areas of the leaf edge are eaten. Planting should be done with spacing that allows for maximum spray coverage; rotate crops to minimise pest pressure; select a production period that will minimise pest pressure; use strategic cultivation and pupae busting; and control weeds. Crowned Slug Moth 71. Grevillea alpina Sweet corn; beans; peas;lettuce; brassica vegetables; greenhouse vegetables; wide range of crops. They might also take a nibble of maple or birch leaves, but there is such little damage it is inconsequential. Other natural spongy moth controls include the nuclear polyhedrosis virus (NPV) and various parasitoids, including wasps and flies that attack the eggs or caterpillars. Specifically, a green version of the full-grown larva exists within the species. [8] This behaviour is costly in terms of energy and can help explain why the moth has evolved such enhanced visual capabilities for efficient feeding. [10], Two separate subspecies, Deilephila elpenor elpenor and Deilephila elpenor lewisii, were recognised in the past, but they are no longer regarded as well-distinguished. Because the poison stays with the insects as they mature through subsequent stages of development, they are toxic to vertebrate predators both as larvae and as adult butterflies.
