Plant Parasites of Europe

leafminers, galls and fungi



Whiteflies are distantly related with the jumping plant lice, Psyllidae. The adult insects have two pairs of feeble wings and sap-ucking mouth parts. The long-stalked eggs are deposited on the host plant, often in a circle around the female. There are four larval stages, of which only the first is mobile. Later stages remain attached to the plant by their stylet. Identifications are mostly based on the final larval stage, generally named the “puparium”. The puparium is the most conspicuous stage, often also the hibernating stage.
