Hyles euphorbiae, the spurge hawk-moth, is a European moth of the family Sphingidae. This hawk moth is used as an agent of biological pest control against the noxious weed leafy spurge (Euphorbia virgata), but usually only in conjunction with other agents.

The Spurge Hawk-Moth - Fore wings grey, with an almost square olive-brown blotch; at the base another olive-brown blotch near the middle, and a long oblique band of the same colour, commencing in a point at the extreme apex of the wing, and gradually growing wider until it reaches the margin, where it is very broad: hind wings pink, with a black blotch at the base, and a black band half-way between this black blotch and the margin, and a snowy-white blotch at the anal angle: thorax and body olive-brown, with a white line on each side of the thorax just at the base of the wings; this line runs on each side along the head just above the eye, and the two meet at the nose; the body has on each side at the base two square black spots and two square white spots, and beyond...

Likely
About 40% of wildlife watchers report a Leafy Spurge Hawkmoth sighting in Vanoise National Park on a given day, based on 60 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 308 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
August
In that month about 50% of wildlife watchers report a Leafy Spurge Hawkmoth in Vanoise National Park on a given day, against under 5% in October and December–May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Leafy Spurge Hawkmoth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 11 parks where we can rate Leafy Spurge Hawkmoth sightings, Vanoise National Park has the highest daily chance: about 40%. Next come Kiskunság National Park (Hungary, about 30%) and Ecrins National Park (France, about 30%).
GBIF citizen-science records
It is estimated from how often the Leafy Spurge Hawkmoth is recorded against all the insects logged in Vanoise National Park (60 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.
