HabitatThe eastern tailed blue is found in open sunny areas like fields, meadows, roadsides, and forest glades. DietThe eastern tailed blue caterpillar eats a variety of plants in the pea family including cow vetch, clover, alfalfa, and wild pea. The butterfly feeds on flowers close to the ground like clover, shepherd's needle, wild strawberry, winter cress, cinquefoils, and asters. Life Cycle
The male eastern tailed blue perches on potential host plants and waits for a female. The female lays her single eggs on the flower buds or stems of a host plant like white or red clover, beans, wild pea and trefoil. There are usually three broods a year. The last year will overwinter in bean and pea pods. |
