Description
|
Tiny parasitic wasp with orange coloured abdomen and black head and thorax. Lays its eggs into second, third and fourth nymphal stages of whitefly.
The encarsia egg then hatches inside the whitefly scale and the wasp larva feeds inside the scale.
The scale will turn black within two weeks and a wasp will emerge soon after.
