I have started spotting the tiny cassius blue butterfly throughout the garden. It is such a fast flyer, making it hard to photograph.

In all the years I have had its host plant, plumbago, I have never spotted the caterpillars, or the chrysalis.

Its wingspan is only 15-22 mm. The egg is flattened and blue. The butterfly will lay the egg on flowers, flower buds or the developing seed pods of the plumbago.

There are two eyespots on the margin of the hind wing. The males are pale to bright blue above, while the females have a bluish-white to white above the basal area of the wing, as well as broad dark borders.

The larvae are also small, as it is approximately only .5 inches in length and are green with faint dark markings, or a patterned white faint marking.
