Cyrtacanthacris aeruginosa
In 3 days ~10% in a week ~30%
Cyrtacanthacris aeruginosa or simply green tree locust is a large species of grasshopper that can be found in the grasslands of Africa. The species is univoltine, that is, it only produces one brood of offspring per year, furthermore it also experiences egg diapause, meaning that the eggs have a phase of suspended or arrested growth. In terms of overwintering strategy, Aeruginosa adults mate and then the female lay the eggs and die before the dry season, the eggs stay in diapause for 7 months and take 45–67 days to incubate.

Rare
Under 5% of wildlife watchers report a Green Tree Locust sighting in Kruger National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 430th most-seen of the 748 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.
February to April
In those months about 10% of wildlife watchers report a Green Tree Locust in Kruger National Park on a given day, against under 5% in May to January, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Green Tree Locust 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 Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Green Tree Locust sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Green Tree Locust is recorded against all the insects logged in Kruger National Park (9 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.
