Ariadne merione, the common castor, is an orange butterfly with brown lines whose larvae feed almost exclusively on castor (Ricinus communis). It is similar in appearance to Ariadne ariadne, the angled castor. This species is found in South and Southeast Asia. Their wingspan ranges between 30 and 35 mm. Like others in the family Nymphalidae, their front two legs are small and unused, effectively making them four legged. These smaller appendages are covered with long hairs, giving them the characteristic brush look.
Male: Upperside brownish ochraceous. Forewings and hindwings crossed by slender, somewhat obscure, very sinuous or zigzag dark basal, two subbasal and two discal lines disposed in pairs, followed by a single, sometimes double, postdiscal and a single subterminal slender line. All these lines more or less interrupted anteriorly on the hindwing, which has a smooth unmarked uniform appearance from costa to subcostal vein and vein 5. On the forewing there is in addition a series of obscure spots between the postdiscal and subterminal markings, arid a small white subcostal spot before the apex.

Possible
About 30% of wildlife watchers report a Common Castor Butterfly sighting in Hyderabad on a given day, based on 235 verified sightings from GBIF citizen-science data. It is the 17th most-seen of the 318 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 50% of wildlife watchers report a Common Castor Butterfly in Hyderabad on a given day, against under 5% in February, the lowest month. That is one of Hyderabad's wettest months, with about 150 mm of rain against almost none in December.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Castor Butterfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 29
Of the 29 cities where we can rate Common Castor Butterfly sightings, Hyderabad ranks 9th at about 30%. The best odds are in Jabalpur (India, about 40%), Salem (India, about 40%) and Raipur (India, about 40%).
Same family: Nymphalidae
The closest relatives of the Common Castor Butterfly that you can see in Hyderabad (family Nymphalidae, Brush-footed Butterflies) are Plain Tiger Butterfly (about 40%), Lemon Pansy (about 40%) and Common Evening Brown (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Castor Butterfly is recorded against all the insects logged in Hyderabad (235 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.
