In 3 days ~20% in a week ~50%
Xylophanes germen is a moth of the family Sphingidae. It is known from Mexico, Costa Rica, Guatemala and is found from Venezuela to Bolivia. The wingspan is 72–85 mm. The forewing has a crenulated outer margin. The forewing upperside ground colour is olive green-grey. The transverse lines are indistinct, the basal and two antemedian lines are curved outward from the inner margin and then back towards the costa. The three postmedian bands are running transversely across the wing, distal to which may be a variably developed paler patch and an orange-brown patch.
Adults are probably on wing year-round. The larvae feed on Psychotria correae, Psychotria elata, Psychotria eurycarpa and Exostema mexicanum and possibly other Rubiaceae species. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Xylophanes germen is recorded against all the insects logged in Monteverde Cloud Forest Reserve (22 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.
