Sciapteron robiniae Hy. Edwards, 1880
* phylogenetic sequence #079125
Explanation of Names
Specific name robiniae is from the plant genus Robinia, one of the larval hosts Edwards listed in his description.
Two other forms have been recognized: P. r. perlucida , and P. r. palescens.
Wingspan: ♂ 23-30 mm, ♀ 30-36 mm. (1)
Forewing length 11-18 mm. (2)
Adult - colored almost exactly like a paper wasp. Mostly yellow, first three abdominal segments black. Head is black, with yellow facial scales. FW orange brown with darker veins; HW clear with a deep yellow discal mark, fringed with dark brown scales. Antennae of males are bipectinate, simple in females.
Larva - white to grayish white with brown head and thoracid shield. (1)
From Alaska, along the Pacific coast to southern CA, inland to the desert Southwest, throughout the Rockies, east to North Dakota and Kansas. Pohl et al. adds Alberta, Canada. (2)
Type Location: Virginia City, Nevada.
Larvae bore the wood of poplars (Populus
, Salicaceae) and willows (Salix
, Salicaceae) and ornamental birches in Betula
(Betulaceae), often in trees already weakened by wood-boring beetles. Edwards reported them on black locust
, Fabaceae), as well as Populus
, but later researchers do not mention locust. (2)
Eggs are laid in bark crevices and wounds and hatch in about 20 days. Overwinters as larva in a pupal chamber which is capped with silk. Pupation occurs in late May or June of the larva's second year. (2)
