Hawthorn dark bug
Heterocordylus malinus Reuter
Hemiptera: Heteroptera: Miridae
The young adult is black with red wing markings (A), which disappear a few days after it metamorphoses into an adult.
Most fruit-growing states and provinces in eastern North America.
Attacks apple and pear. Nymph causes slight depressions on the fruit that disappear as the fruit develops.
The tarnished plant bug (Lygus lineolaris) can be distinguished by its coloration, particularly its cream-colored scutellum. Contrast also with apple brown bug (Atractotomus mali); apple red bug (Lygidea mendax Reuter) and pear plant bug or green apple bug [Lygocoris communis (Knight)].
Application of broad-spectrum insecticides, if necessary, soon after petal fall (seldom required).
