Explanation of Names
aureonotata = from the Latin aureo ('made of gold or golden') + notāta ('marked'); 'gold-marked'
Size
20-22 mm length (1)
Identification
In this area, a distinctive thread-waisted wasp. The coloration is black with slight blue reflections, two silvery to golden patches of setae on each side of the thorax, and another pair on the propodeum. Males have more extensive pile on face than do the females.
Range
e. NA to TX and Costa Rica(2)
Habitat
Old fields near deciduous or other(?) woodlands. The wasp is commonly found on wildflowers with large clusters of blossoms, such as Queen Anne's Lace. Mating pairs on flowers are common.
Season
Jun-Oct in NC(3); in MI, Jun-Sep, mostly Jul-Aug(4)
Food
Adults take nectar; larvae feed on larval Noctuidae, Notodontidae (especially), Sphingidae, and Hesperidae (host list - web archive)
Life Cycle
Female digs burrow and provisions it with a single large caterpillar--see species account (4).
Caterpillars of prominent moths are the preferred hosts:
Remarks
It is odd that this distinctively marked, common (if not abundant) North American wasp was missed by early entomologists, such as Thomas Say. The species was not described formally until 1888 based on collections from the Yucatan Peninsula in Mexico (original description).
