Identification
This is Ogcodes dispar, the males are typically bright yellow-orange. The thorax should be dark for O. rufoabdominalis. The species is widely distributed in eastern North America, though uncommonly encountered. Both sexes of rufoabdominalis should have a black thorax making them obviously bicolored (but the reverse of this one). Males of O. dispar are typically yellow-orange all over, while the female is darker (especially the abdomen). … Dennis Haines, 6 December, 2007
