Cyrtophorus verrucosus, commonly known as the ant-like longhorn beetle or ant-mimic longhorn beetle, is a species of beetle in the family Cerambycidae. It is native to North America, more specifically southern Canada and the eastern United States.
C. verrucosus is a specialized ant mimic, even moving in a manner similar to an ant. It has varying amounts of red and black in two forms (the red thought to be mimicking Camponotus chromaiodes and the black Camponotus pennsylvanicus). The pronotum has knobs at its base, two white lines of setae near the center. It is usually between 7 mm (0.28 in) and 11 mm (0.43 in) in length.
This species inhabits deciduous forests and is sometimes found on spring flowers, from which adult beetles extract pollen and nectar. Larvae develop in and feed on hardwood trees, most commonly in the genera Acer, Betula, Cercis, Pinus, and Ulmus. Adult beetles are usually active between March and July.
It is widely believed that due to biodiversity loss, there has been a decrease of C. verruscosus in the Ontario region. In the last 100 years, over 18,000 specimens have been collected, and the accumulation... Wikipedia →

Rare
Under 5% of wildlife watchers report an Ant-Like Longhorn Beetle sighting in Toronto on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 635th most-seen of the 1689 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 an Ant-Like Longhorn Beetle in Toronto on a given day, so our monthly data shows no clear season.
Among the best
Of the 6 cities where we can rate Ant-Like Longhorn Beetle sightings, Toronto ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Minneapolis [Saint Paul] (United States, under 5%) and Philadelphia (United States, under 5%).
Same family: Cerambycidae
The closest relatives of the Ant-Like Longhorn Beetle that you can see in Toronto (family Cerambycidae, Longhorn Beetles) are Red Milkweed Beetle (about 10%), Locust Borer (about 10%) and Banded Longhorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ant-Like Longhorn Beetle is recorded against all the insects logged in Toronto (22 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.
