Species Psylla carpinicola

Psylla carpini Fitch, 1851 nec Forster, 1848

Psylla cephalica Crawford, 1914

Psylla carpinicola Crawford, 1914

4mm (1)

Color variable from light green to reddish brown in mature individuals; wings clear to slightly yellowish fumate, veins sometimes green. Antennae twice as long as width of head; female genitalia very long, longer than rest of abdomen, with both dorsal and ventral valves apically upcurved; male genitalia with proctiger bent in apical third (1). Great variability in regards to the deflection of the head, the genal cones, and the venation; more southerly material exemplified by greater arch in Cu1 vein.

Eastern North America (1)

Host: American hornbeam (Carpinus caroliniana, Betulaceae) (1)

Nymphs apparently produce a white waxy flocculence, similar to other Psylla spp.:

The only psyllid known to use C. caroliniana as a host (2).

Psylla buxi, Cacopsylla striata, and C. dilonchi all have similar, elongate female genitalia, though the apically upcurved valves in P. carpinicola should serve to distinguish this species.
