Snowy Tree Cricket

Joseph Berger, Bugwood.org
Oecanthus fultoni.    Snowy Tree Crickets are generally pale green with transparent wings. Antennae with black spot on 1st and 2nd segments. Male's fore wings paddle-shaped, held flat over back, concealing all but tips of folded hind wings and short cerci. Female's fore wings narrow, curved closely around body. Nymph is almost white.

Food Adult feeds on aphids and caterpillars. Nymph eats flowers, foliage, and young fruit. Locally they have been damaging cherry laurel, cotoneaster, rhododendron. High temperatures and drought may cause earlier feeding injury than the usual August in the Maryland area. 

The snowy tree cricket is sometimes called the “thermometer cricket” because its chirps are easily countable and their rate correlates well with the temperature at the cricket. In eastern United States, Fahrenheit temperature can be estimated by counting the chirps in 13 sec. and adding 40.

Female selects mate and nudges male until it stops singing. After mating, female cuts pinlike holes in thin bark of woody branches, dabs excrement inside, embeds eggs, and coats them with secretion. They overwinter and hatch in spring. Nymphs attain maturity by midsummer.
