Although the eastern tailed-blue is one of our most beautiful butterflies, it is often overlooked simply because it is so small. This butterfly is about the size of the fingernail on your little finger (0.75-1.0″).
The wings of the male are powdery blue on top. On the other hand, the topsides of the females’ wings are brownish- gray. The undersides of both the male and female’s wings are silvery gray and speckled with dark spots. The hindwings of both display one or two orange and black spots near the trailing edge of their hindwings. In addition, a short thread-like tail extends beyond the border of each hindwing. Since these tails are so fragile, they often break off.
Eastern tailed-blues are weak flyers are spend their entire lives within a few feet of the ground. Consequently, if you are not looking for them, they often go undetected.
Eastern tailed-tailed blues commonly visit flowers in our backyards. However, they also inhabit fields and abused landscapes.
The list of host plants for this butterfly includes beggarweed, bush clovers, and clovers.
The eastern tailed-blue can be seen throughout the state. This petite butterfly annually produces several generations (flights). However, the best time of the year to see this butterfly is from March into October.
Currently the eastern tailed-blue is the most abundant butterfly flying about my neighborhood.
