The one pictured here is the Two-striped Planthopper (Acanalonia bivittata) and they are considered the most common of all planthoppers in the United States. Worldwide there are 63 species within this genus, 18 of them are found in the United States. They are almost always green with a reddish-brown stripe along the inner edge of the wing. Occasionally you may find a pink specimen. They measure 1/4 to 15/64 inches in length (3 to 6 mm).
Mating probably takes places in late summer or early fall and the female will use her sharp ovipositor to slice into twigs or the stems of many of the plants they feed on, like blueberries for instance. She will lay her eggs within the slit she creates and the eggs overwinter. When spring arrives the eggs hatch and the nymphs superficially resemble their parents. They reach the adult stage by late summer and the cycle will begin again.
