Microcentrum rhombifolium is a species of insect in the family Tettigoniidae. Common names include greater angle-wing katydid, broad-winged katydid, and angular-winged katydid. They live across North America in trees and shrubs. Adults are active in late summer and autumn and have a "ticking" call. They have been reported to chew on the peels of citrus crops, resulting in minor damage.
Microcentrum rhombifolium have a green, leaf-like appearance with long, threadlike antennae and feet divided into four segments. Adults reach 50–65 millimetres (2.0–2.6 in) in length and are rhombus-shaped. M. rhombifolium looks similar to M. retinerve, but the two species may be distinguished by the shape of their pronota. In M. rhombifolium, the front edge of the pronotum has a small bump in the middle. M. retinerve does not have this bump.

With luck
About 10% of wildlife watchers report a Greater Anglewing sighting in Toronto on a given day, based on 123 verified sightings from GBIF citizen-science data. It is the 189th 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 30%, if each day is a fresh chance.
August to October
In those months about 10% of wildlife watchers report a Greater Anglewing in Toronto on a given day, against under 5% in November to July, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Greater Anglewing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 21 cities where we can rate Greater Anglewing sightings, Toronto ranks 8th at about 10%, level with the leaders once rounded. The best odds are in Denver (United States, about 10%), Salt Lake City (United States, about 10%) and Minneapolis [Saint Paul] (United States, about 10%).
Same family: Tettigoniidae
The closest relatives of the Greater Anglewing that you can see in Toronto (family Tettigoniidae, Katydids) are Oak Bush-Cricket (about 10%) and Black-Legged Meadow Katydid (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Greater Anglewing is recorded against all the insects logged in Toronto (123 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.
