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 →

Rare
Under 5% of wildlife watchers report a Cimbex americana sighting in Houston on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 847th most-seen of the 1057 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 Cimbex americana in Houston on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Cimbex americana sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 cities where we can rate Cimbex americana sightings, Houston ranks 5th at under 5%. The best odds are in Anchorage (United States, about 10%), Dallas (United States, under 5%) and Austin (United States, under 5%).
Same order: Hymenoptera
The closest relatives of the Cimbex americana that you can see in Houston (order Hymenoptera, Ants, Bees, Wasps, and Sawflies) are Eastern Carpenter Bee (about 20%), American Bumble Bee (about 20%) and Red-Marked Pachodynerus Wasp (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cimbex americana is recorded against all the insects logged in Houston (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.
