Description of the gall
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. Adults can also be found in the gall. The adults usually overwinter in leaf litter but can also spend the winter in the gall.[3] Species of Laurus galled include the Azores laurel (Laurus azorica), bay tree (Laurus nobilis), Laurus novocanariensis and Persea indica.[2]
