|A BIT ABOUT BUGS
The Triozidae contains a large number of species that have generally pointed forewings, and the three main veins joinging at one point. Many species are difficult to separate, or impossible without dissection.
B. albiventris has a characteristic reddish colouring that darkens to black with maturity; there are no pale longitudinal lines on the dorsum of the thorax. The underside of the abdomen is strikingly pale. Can be separated from the very similar (but rarer) B. curvatinervis from the genitalia, or by the apical cell of the forewing being substantially larger in the latter.
The species is common throughout the UK on Salix species. Adults overwinter on conifers.
Adult: All year
Length 3.5-4 mm
