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 Zion National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 65th most-seen of the 114 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
September and October
In those months about 20% of wildlife watchers report a Greater Anglewing in Zion National Park on a given day, against under 5% in December 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.
Only Zion National Park, in our data
Zion National Park is the only park on Wallace's Line with enough records to rate Greater Anglewing sightings: about 10% of wildlife watchers there report one on a given day.
Same order: Orthoptera
The closest relatives of the Greater Anglewing that you can see in Zion National Park (order Orthoptera, Grasshoppers, Crickets, and Katydids) are Green Bird Grasshopper (about 20%), Pallid-Winged Grasshopper (about 10%) and Yarrow's Grasshopper (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 Zion National Park (7 verified sightings from 2019 to 2026), 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.
