Butterflies of the Amazon and Andes
Tessman's Blue
Leptotes bathyllos  TESSMANN, 1928
Family - LYCAENIDAE
subfamily - POLYOMMATINAE
Leptotes bathyllos, Medellin, Colombia, Chris Orpin
Introduction
About 120 members of the cosmopolitan subfamily Polyommatinae occur in the neotropical region. Most are confined to the temperate grasslands of the high Andes, although a few species occur at much lower altitudes.
There are Leptotes 12 species, the commonest and most well known being cassius, which is found in California, Mexico, Central America, most of the Caribbean islands, and in Venezuela and Surinam. The other species are marina from Mexico, perkinsae from Jamaica, hedgesi from Cuba, idealus from Hispaniola, andicola from Ecuador and Colombia, delalande from Ecuador, parrhasioides from the Galapagos Islands, trigemmatus from Chile; and callanga, bathyllos and lamasi from Peru.
The precise distribution of bathyllos is uncertain due to confusion with other Leptotes species. The type specimens are from Peru. If my determination of the illustrated insect is correct, the range also extends into Ecuador and Colombia.
Habitats
This species is found in disturbed grassy habitats at elevations between about 200-1600m. It is most often seen along roadsides or regenerating grassy clearings in secondary rainforest.
Lifecycle
To be completed.
Adult behaviour

The butterflies are active only in hot sunshine, at which time small numbers can be found flying in sheltered grassy areas. In overcast or hazy conditions they roost in a head-downward posture, on flowerheads, or on the stems of herbaceous or woody plants.
