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 San Luis Potosí on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 91 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.
April
In that month about 30% of wildlife watchers report a Greater Anglewing in San Luis Potosí on a given day, against under 5% in March and May–January, the lowest months. That is one of San Luis Potosí's driest months, with about 5 mm of rain against 110 mm in July.

GBIF citizen-science records
It is estimated from how often the Greater Anglewing is recorded against all the insects logged in San Luis Potosí (5 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.
