Neodiprion lecontei is a species of sawfly in the family Diprionidae native to eastern North America, commonly known as the red-headed pine sawfly or Leconte's sawfly. The larvae feed on the foliage of many species of native and imported pines. This species was named after John Lawrence LeConte, an American entomologist of the 19th century.
It forms part of the N. lecontei species group, which consists of a clade of about twenty closely related species which have been intensively studied. The genome has been sequenced and consists of 330 MB arranged on seven chromosomes.
The adult N. lecontei has membranous wings and a broad waist and is between 5 and 8.5 mm (0.20 and 0.33 in) long, with the males being somewhat smaller than the females. Males have feathery antennae while females have serrated ones with nineteen segments. Males are entirely black and are more slender than the robust females, which have reddish-brown heads and thorax, and mainly black abdomens, sometimes with white on the sides. The larvae resemble the caterpillars of lepidopterans; young larvae are whitish with brown heads while older larvae are yellowish-green with up to eight longitudinal... Wikipedia →

Rare
Under 5% of wildlife watchers report a Red-Headed Pine Sawfly sighting in New York City on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 768th most-seen of the 1623 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Red-Headed Pine Sawfly in New York City on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Red-Headed Pine Sawfly is recorded against all the insects logged in New York City (20 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.
