Cimbex americanus, the elm sawfly, is a species of sawfly in the family Cimbicidae. This is a very large species of Hymenoptera, with adults measuring 3 cm and larvae reaching 5 cm long. If captured, adults may buzz and use their powerful spiny legs defensively. However, like other sawflies, this species does not possess a sting. The wasp Opheltes glaucopterus is a parasite of the prepupae stage of this sawfly. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cimbex americana is recorded against all the insects logged in Anchorage (7 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.
