Ischnoptera snodgrassi
cucaracha
Scavenger; in humid forest and pampa habitats; February-June and September. Found under leaves on very wet ground covered with abundant and luxurious vegetation of ferns, shrubs and vines; usually under large rocks. Wings reduced to wing pads, probably descended from winged colonist. The flightless condition has not prevented it from spreading to all volcanoes on Isabela.
