How to identify it

  • Adults are about 1/8 inch (3.5 to 4 mm) long, shiny and oblong-oval, brown to dark brown or orange-winged on top and orange underneath with a black face.[1][2]
  • Nymphs are bright red to vermilion with white antennae and feet, and are well camouflaged on red azaleas.[1][2]
  • A beak for sucking juices separates it from similarly colored beetles; disturbed bugs dodge to the underside of the leaf.[2]

Look-alikes

Look-alikeHow to tell them apart
Azalea lace bugA more damaging azalea pest; the azalea plant bug does far less harm to the plant's looks.[1]

Where it lives

Generally distributed from Ontario south to North Carolina and west to Missouri.[2]

US map: public records from 14 states since 1990 (GBIF).

Biology and life cycle

Eggs overwinter in azalea stems and hatch around bloom time, in early to mid-May near Harrisburg, Pennsylvania.[1][2]

There are five nymphal stages and one generation a year; adults appear in early June and are gone by mid-July, some moving to raspberries, spirea and plum.[1][2]

Damage and signs

  • Nymphs feed on petals and stamens and may slightly deform flowers; the bug probably matters only on azaleas grown for seed.[1][2]

Health risk

It often bites gardeners working in azaleas, leaving a painful, chigger-like welt.[1][2]

Control

Pesticides

Control is rarely needed; many products labeled for plant bugs work if it is.[1]

Common questions

What tiny red bug bit me while I trimmed my azaleas?
Most likely an azalea plant bug nymph or adult, active around azalea bloom.[1][2]
