|A BIT ABOUT BUGS
Cacopsylla is a large and difficult genus with genal cones and a pterostigma; many species cannot be reliably identified without examining the genitalia.
One of a few species of Psylla that have a black spot on the inside edge of the forewing, and it is generally larger than in the previously very rare (but expanding) C. pyri. The body colouration here is typical, but the species exists in two generational morphs; later in the summer, the wings are often cloudy.
A common species on pear trees in the south of England, but rarer further north.
Adult: All year (overwinters on Pyrus spp.)
Length 3.3-4 mm
