Scott Alston-Smith, Matthew J.W. Cock

Abstract


Here we report another mass movement of a lycaenid in Trinidad: Nicolaea besidia (Hewitson), a species not previously recorded from the island. On 18 November, 1979, the first author and the late F. Clive Urich were collecting on the seashore at St. Quintin Estate, Columbus Bay, Cedros, at the end of the southwestern peninsula of Trinidad, about 12 km from the South American mainland. It was late morning, between 1000 and 1200 h, when we noticed lycaenids flying in off the sea from the direction of Venezuela and settling on the mangrove trees behind us.
