    Eastern-tailed Blue Butterfly - (Cupido comyntas)

    The charming Eastern-Tailed Blue Butterfly is a small, but mighty common, visitor to flowers.

    Picture of Eastern-tailed Blue Butterfly
    Staff Writer (1/13/2014): The Eastern-Tailed Blue Butterfly is a member of the Gossamer-Winged Butterfly group. They appear light and airy, floating through flight with delicate wings. This species is a part of the Blues tribe, where most members are shades of blue (pale blue to rich royal blue). It enjoys sitting on flowers and stems with its wings open, occasionally rubbing the hindwings together as if to scratch an itch. It is the only Blue on the eastern part of the continent with a 'tail' on the ends of its wings.

    Males have royal blue wings when they are open and females are more brown. When closed, both genders have whiter blue wings with black/gray markings. They have two orange eyespots on their lower hindwings that is thought to help confuse bird predators. If the bird mistakes the eyespot for the head and pecks at it, only a small part of the wing is damaged and the butterfly can escape complete annihilation.

    This small butterfly can be found in parks, gardens, meadows and anywhere else flowers are abundant. Males tend to socialize at puddles or wet mud in what are called "puddle parties".

    The caterpillar of the Eastern-Tailed Blue Butterfly enjoys chewing the leaves of flowers and a variety of bean plants.
