Kleidocerys resedae, birch catkin bug

 

 

 

Family: Lygaeidae

Subfamily: Ischnorhynchinae

Length: 3-4 mm

 

Some of the key traits of Kleidocerys resedae include: Corium hyaline to yellowish-hyaline with several dark spots. Antennal segments one and four darker than two and three. Scutellum red-brown at apex. Three rows of punctures on the clavus. Legs red-brown with tarsi usually darker. Head and pronotum punctate.

Kleidocerys resedae seems to have been introduced to North America from Europe (and it is found in Siberia as well). Its Nearctic range extends from Alaska and Yukon to Newfoundland, south to California and Mexico.

This insect congregates at times; Blatchley (1926) tells how "it was once swept by scores from the stems of dead asters of the previous year" in Indiana, "while on August 12 it was noted by the hundreds in all stages, the adults mating, on a hedge row of Spirea."
