Junk Bug (Lacewing Larva)

Natural Habitat

Gardens, agricultural fields, forests, and shrublands; typically found on leaves, branches, tree trunks, and sometimes on walls or structures where aphids are present.

Diet & Feeding

Carnivorous and voracious; primarily feeds on aphids (often called 'aphid lions'), as well as mealybugs, thrips, mites, whiteflies, and insect eggs.

Behavior Patterns

The most distinctive behavior of this larva is camouflage. It attaches hollowed-out carcasses of its prey, bits of moss, bark, and other debris to hooked bristles (setae) on its back. This 'trash packet' hides it from birds and larger predators and allows it to sneak up on unsuspecting prey.

Risks & Benefits

Extremely beneficial to the ecosystem and agriculture as natural pest control. They are harmless to humans, though they may occasionally deliver a tiny, harmless nip if handled. They are highly valued by gardeners.
