Bactericera salicivora (Reuter, 1876)

3.5-4mm (2)

General color variable, from orange to red to dark reddish-brown; head and genal cones usually reddish but sometimes dark brown to black; abdomen darker dorsally and pale ventrally; antennae 1.5x width of head, pale basally and black apically; anal angle of forewing often darkened; female genital segment short, about as long as preceding abdominal sternite (3)

Holarctic, widespread in North America (4)

Salix (3)

Nymphs occur on the underside of leaves, rarely in great abundance, forming shallow blister-like depressions. They do not produce any conspicuous waxy secretion (5)

Bactericera minuta is also widespread and common on Salix, and though also extremely variable the head and cones are typically black, the forewing typically lacks darkened anal angle and the female genital segment is usually twice as long (except in var. arizonae) (3)

B. californica is similar in many respects, but with the forewing darkened along vein R+M+Cu:
