Rekoa meton Cramer

NOMENCLATURE.—Papilio meton Cramer, 1779: Cramer (1779–1780) described and illustrated a Surinamese male of P. meton. Although the figure shows a specimen with two hindwing tails (there should be one), it can be confused with no other hairstreak species. There is a male with one tail in the Rijksmuseum van Natuurijke Historie (Leiden) that fits the original figure and that can be designated a lectotype if one is ever deemed necessary.

Hesperia augustus Fabricius, 1793: Fabricius (1793) described H. augustus from an “American” female with a brief description. Butler (1870) synonymized this species to P. meton. Although no type specimen is known (Zimsen, 1964), Jones' unpublished figure of H. augustus in the BNMH library supports this synonymy.

GEOGRAPHICAL VARIATION.—As is true for R. stagira and R. marius, the ventral wing pattern of R. meton varies geographically (Figures 65, 68, 69). Three major wing pattern characters vary, each of which changes in different geographic regions. First, females from southern Brazil (Rio de Janeiro south to Santa Catarina) are blue above, while those from central Brazil (Minas Gerais) and Paraguay have only a blue tinge and those from further north are white. Second, the basal line on the ventral hindwing is present in specimens south of about 20° S latitude, is present in about half of the specimens across the Amazon basin from Peru to the Guianas, and is absent in Central American specimens. Third, specimens from the Amazon basin have a light yellow patch in the middle of the ventral hindwing that contrasts with the remainder of the wing. In specimens to the south and north of the Amazon Basin, the patch is usually darker so that it does not contrast with the rest of the wing.

IDENTIFICATION.—Identification of R. meton has never posed a problem. Although the ventral wing pattern of specimens in the south part of the range could be confused with that of R. malina, R. meton is larger, usually has an “eyespot” at the base of the ventral hindwing, has a different wing shape, and has the base of dorsal hindwing vein Rs covered with white scales as opposed to the brown or blue scales of R. malina (Figures 64–69, 71–74).

ECOLOGY AND BEHAVIOR.—Habitat: Rekoa meton occurs throughout most of the neotropics from sea level to 2000 m elevation in wet and dry habitats, but rarely above 1000 m at the north and south extremes of its range.

Dispersal: Rekoa meton appears to be a moderately dispersive species. Two females have been collected at Portachuelo Pass (Rancho Grande), and one female at the Cerro Campana ridge. It occurs on Isla Margarita and Trinidad, but is not recorded from other offshore islands.

Foodplant Records: There are no larval foodplant records nor have nectar sources used by adults been noted.

Territoriality: I suspect that males perch in the early afternoon. More than 15 years ago in Melgar (Colombia), before I knew that male hairstreaks set up mating territories, I saw males in the early afternoon landing on the tops of bushes about 4–5 m high. The similar observations of Barcant (1970) lead me to believe that the specimens I saw in Melgar were territorial males.

Wing Pattern and Predation: Of 37 specimens collected at Villavicencio, Colombia (Robbins, 1981), 9 showed symmetrical wing damage indicative of an unsuccessful predator attack to the hindwing anal angle.
