Oblique Streaktail (Allograpta obliqua) lives in tropical forests across Southeast Asia. It feeds on flies and aphids.
Fascinating facts about the Oblique Streaktail
- At just 6-7 mm long, the oblique streaktail looks like a tiny flying stripe-patterned brush-stroke, its thorax painted with yellow bands and its abdomen marked by four longitudinal yellow stripes or spots on the fourth and fifth tergite. Its face is yellow and lacks a complete median stripe, while males sport holoptic eyes that meet at the top of the head and females keep theirs separated (dichoptic). Even its eggs are minuscule, white, oval and about 0.84 mm long, and the bumpy, slug-like larvae grow to 8-9 mm.
- Allograpta obliqua's life cycle is a rapid aphid-hunting sprint: females lay eggs on leaves or branches right next to aphid colonies, the eggs hatch in just two to eight days, and the emerging larvae immediately start devouring the soft-bodied pests. While the larvae act as voracious aphid predators, the adults switch roles to become pollinators, flitting from flower to flower. Adults are even present year-round in the southern part of their range.
