Biology:Lauritrioza
Lauritrioza is a monotypic genus of sap-sucking Psyllid bugs in the family Triozidae.[1] The single species Lauritrioza alacris (originally described as Trioza alacris) creates galls on the leaves of Laurus species: mostly in Europe, including the British Isles, but also introduced to western N. America.[1]
Description of the gall
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.[2] Species of Laurus galled include the Azores laurel (Laurus azorica), bay tree (Laurus nobilis), Laurus novocanariensis and Persea indica.[3]
