I was intrigued to find out why it was given its name and it turns out it was named after the British Prime Minister Neville Chamberlain! He was born in Birmingham on 18 March 1869 and became keen on natural history. At the age of 21 he was sent by his father to the Bahamas to establish a sisal plantation that his father thought would revive the family fortunes. The plantation, established the following year on North Andros Island, failed in 1896 and he returned home. While there he had collected many butterflies and other insects and in 1898, Butler described a new Eurema endemic to the Bahamas and named it after its collector Neville Chamberlain. The species has subsequently been reassigned to a different genus and is called Pyrisitia chamberlaini. On his return to England Neville Chamberlain entered politics and went on to become the Chancellor of the Exchequer and then Prime Minister from 1937-1940.
And another big thank you goes to Frank Model who has kindly allowed me to use his lovely photo of Mexican Ruby-eye Carystoides mexicana which has been recorded just once in Cuba in 2002. Frank's photo was taken in NE Mexico. Thank you Frank.
