Aleurodicus dispersus Russell, 1965

spiralling whitefly

broadly polyphagous

Aleurodicus dispersus: eggs

the eggs are not deposited in the usual circle, but in a rough spiral, which gave the species its vernacular name (photo copied from Pacific Pests and Pathogens – Fact Sheets)

parasite

The two Aleurodicus species *both introduced from South America) are well characterised by the oviposition pattern: not as usual in a circle, but in a long sinuous line. Of these two the adults of dispersus have four grey spots on the fore wings.
