Scolia dubia, also known as the two-spotted scoliid wasp or a blue-winged scoliid wasp, is a species in the family Scoliidae. S. dubia is a 2.0–2.5-centimeter (0.8–1.0 in) long wasp. The body is black from the head through the first or second segment of the abdomen. The second third abdominal segment and beyond are red. The nominate subspecies possesses has the second abdominal segment black and two yellow spots on the third tergite, which are lacking in the subspecies S. dubia haematodes. The wings are violaceous or with blueish reflections.

Males are colored as the female of their respective subspecies but have longer antennae and seven rather than six metasomal segments.

This species ranges from New England to Florida and west to California in the United States. The southern extent of its range extends to Coahuila, Mexico. Females burrow into ground in search of grubs, particularly those of the green June beetle, Cotinis nitida, and... Wikipedia →
