Lytta vesicatoria, also known as the Spanish fly, is an aposematic emerald-green beetle in the blister beetle family (Meloidae). It is distributed across Eurasia. The species and others in its family were used in traditional apothecary preparations as "Cantharides". The insect is the source of the terpenoid cantharidin, a toxic blistering agent once used as an exfoliating agent, anti-rheumatic drug and an aphrodisiac. The substance has also found culinary use in some blends of the North African spice mix ras el hanout. Its various supposed benefits have been responsible for accidental poisonings.
The generic name is from the Greek λύττα (lytta), meaning martial rage, raging madness, Bacchic frenzy, or rabies. The specific name is derived from Latin vesica, bladder. Lytta vesicatoria was formerly named Cantharis vesicatoria, although the genus Cantharis is in an unrelated family, Cantharidae, the soldier beetles. It was classified there erroneously until the Danish zoologist Johan Christian Fabricius corrected its name in his Systema entomologiae in 1775. He reclassified the Spanish fly as the type species of the new genus Lytta, in the family Meloidae.

With luck
About 10% of wildlife watchers report a Spanish Fly sighting in Almaty on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 68th most-seen of the 83 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Spanish Fly in Almaty on a given day, against under 5% in July to April, the lowest months. Those are among Almaty's wettest months, with about 55 mm of rain a month against 20 mm in September.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Spanish Fly sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Spanish Fly sightings, Almaty ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Kyiv (Ukraine, about 10%).
GBIF citizen-science records
It is estimated from how often the Spanish Fly is recorded against all the insects logged in Almaty (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.
