Pyrausta signatalis, the raspberry pyrausta moth, is a moth in the family Crambidae. It was described by Francis Walker in 1866.[2]
Range
[edit]It is found in North America, where it has been recorded from British Columbia to Ontario, south to North Carolina, South Carolina, Texas and Arizona.[3] The habitat consists of aspen parkland and grasslands.
Behavior
[edit]The larvae feed on Monarda species,[4] including Monarda fistulosa, consuming mainly reproductive parts (flowers and seeds)[5].
Life history
[edit]In rearing records from Melrose, Massachusetts, larvae fed on the flowers of beebalm (Monarda), with larvae collected in July and August and pupae found in August and again the following spring; the species overwinters as a prepupa within a cocoon.[6] Adults were recorded in August, and again from June to early July, indicating at least a partial second generation per year in this area.[6]
Parasites
[edit]Several parasitoid insects have been reared from P. signatalis larvae[6]. Tachinid flies recorded include Nemorilla floralis and Phorocera erecta, as well as an unidentified species of Lespesia (cited by Schaffner under the now-synonymized genus name Achaetoneura[a]); this fly emerged one per host in August, over at least two generations a year, with its hibernation stage undetermined.[8]
The braconid wasp Bracon gelechiae has also been reared from P. signatalis larvae, with adults emerging (up to six per host) in June and August.[9]
