With luck
About 10% of wildlife watchers report a Green Drab sighting in Tel Aviv on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 264 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June to September
In those months about 20% of wildlife watchers report a Green Drab in Tel Aviv on a given day, against under 5% in February–March, May and November–December, the lowest months. Those are among Tel Aviv's driest months, with almost no rain against 90 mm in January.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Green Drab sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 6 cities where we can rate Green Drab sightings, Tel Aviv has the highest daily chance: about 10%. Next come Perth (Australia, about 10%) and Johannesburg (South Africa, under 5%).
Same family: Erebidae
The closest relatives of the Green Drab that you can see in Tel Aviv (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Ocnogyna loewii (about 30%), Crimson-Speckled Flunkey (about 20%) and Brown Triangle Snout (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green Drab is recorded against all the insects logged in Tel Aviv (19 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.
