Pyrausta signatalis, the raspberry pyrausta moth, is a moth in the family Crambidae. It was described by Francis Walker in 1866. 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. The habitat consists of aspen parkland and grasslands.
The larvae feed on Monarda species, including Monarda fistulosa, consuming mainly reproductive parts (flowers and seeds). 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. Adults were recorded in August, and again from June to early July, indicating at least a partial second generation per year in this area.
Several parasitoid insects have been reared from P. signatalis larvae. 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); this fly emerged one per host in...

Rare
Under 5% of wildlife watchers report a Raspberry Pyrausta Moth sighting in Montreal on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 431st most-seen of the 926 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Raspberry Pyrausta Moth in Montreal on a given day, against under 5% in July to May, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Raspberry Pyrausta Moth sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 9 cities where we can rate Raspberry Pyrausta Moth sightings, Montreal ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Boston (United States, under 5%), Toronto (Canada, under 5%) and Philadelphia (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Raspberry Pyrausta Moth is recorded against all the insects logged in Montreal (15 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
