Junk bug (also known as Aphid Lion)
Scientific Name: Chrysopa spp. or Ceraeochrysa spp. (larva)
Order & Family: Order: Neuroptera, Family: Chrysopidae (Green Lacewings)
Size: Generally 2 to 6 mm in length (excluding the debris pile carried on their back).
Natural Habitat
Found in gardens, forests, agricultural fields, and occasionally indoors where aphids are present. The larvae attach debris to themselves as camouflage.
Diet & Feeding
Voracious predator; primarily eats aphids, but also consumes thrips, mites, mealybugs, whiteflies, and insect eggs. The adult lacewing is often vegetarian, feeding on pollen/nectar.
Behavior Patterns
The larva builds a protective shell or 'packet' out of debris (dead insect husks, lichen, moss, bark) on its back. This serves as camouflage from birds and as a disguise to avoid detection by the ants that often guard aphids.
Risks & Benefits
Extremely beneficial to ecosystems and gardens as natural pest control. Harmless to humans, though the larva can occasionally give a mild, noticeable nipping bite if handled.
