The combined efforts of generations of resident and visiting
naturalists have helped to make the
butterfly fauna of
Tobago well known. Some 129 species have been recorded on the island of Tobago that has a land area of only 300 km2 (116 mi2) and is approximately 42 km long and 10 km wide.
This list follows Malcolm Barcant (1970) who is the main source of information on the butterflies of Tobago.[1] His book is no longer in print, but used copies are available at booksellers. Barcant gives each species an English common name, but many of these were never taken up. Barcant's English name and the more widely accepted English name are given in the list below. Since 1970 many of the Latin names used by Barcant have also changed. The 2004 catalog of Lamas was used to update the taxonomy.[2]
There is little data on the seasonal distribution or abundance of the listed butterflies. In general, butterflies are more abundant in the wet season. However, in the dry season, when most people visit, and especially if the dry season is a wet one, there are many whites/yellows on the wing. These are hard to identify without capture. Other butterflies commonly seen in the dry season in the south west of the island are the
monarch butterfly (Danaus plexippus), the
white peacock (Anartia jatrophe), the
brown peacock (Anartia amathea), the
West Indian buckeye (Junonia evarete) and the
red rim (Biblis hyperia). Away from the flat south west towards
Arnos Vale, there are many other butterflies to be found, including skippers and blues and the blue tinted handkerchief (Dynamine theseus). In the rain forest, on the main ridge, butterflies are quite scarce at this time of year.
