Description and biology
editTrichagalma formosana is only known from galls on Quercus variabilis and Q. acutissima. New galls appear in August. Adults emerged in December in the lab, but in the wild they might overwinter in the gall and emerge next spring. The galls reach a diameter of 15 mm (0.59 in). Only asexual females are known, measuring about 5 mm (0.20 in) in body length.[1]
