Bay Sucker

Lauritrioza 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. Adults can also be found in the gall. The adults usually overwinter in leaf litter but can also spend the winter in the gall. Species of Laurus galled include the Azores laurel (Laurus azorica), bay tree (Laurus nobilis), Laurus novocanariensis and Persea indica.
