Nymph with waxy secretions
Psylla alni psyllid , a plant-feeding hemipteran in the family Psyllidae .
Distribution [ edit ]
This species is present in the Palearctic realm (from Europe to Siberia and Sakhalin, Kazakhstan, Caucasus) and in the Nearctic realm (Canada and United States of America ).[3] [2]
Description [ edit ]
Psylla alni can reach a body length of about 5–6 mm (0.20–0.24 in ). These rather large psyllids have a green head, body, and legs, and rather long antennae. The costal marginal veins of the wings are green, while the other veins are brown. Adults are initially green, later becoming orange, brown, or reddish. The nymphs are usually covered by white waxy secretions.[4] in ).
Biology [ edit ]
Adults can be found from June to October. This species has one generation a year (univoltine ) and overwinters as an egg.
It is monophagous on most Betulaceae (Alnus glutinosa Alnus hirsuta Alnus incana Alnus japonica Alnus viridis [4] [5]
