Lauritrioza alacris [2] Trioza alacris is a sap-sucking hemipteran bug in the family Triozidae which creates galls on the leaves of Laurus species.

Trioza alacris causes the edges of leaves to thicken and roll downwards forming pale, elongated pouches.

The galls can house two generations in a summer, of up to thirty pale-green nymphs, which are covered in a white wax.

The adults usually overwinter in leaf litter but can also spend the winter in the gall.
