Description and Identification
Caterpillar
The Summer Azure caterpillar is a sight to behold, with its light green or occasionally whitish-green body adorned with a distinctive mark resembling a backbone. This mark features an intricate pattern of light maroon, dark green, and yellow stretching from its head to the tail. Feeding primarily on the leaves and flowers of host plants, this larva plays a crucial role in the early stages of the Summer Azure’s life cycle.
Pupa
Transforming into a pupa, the Summer Azure enters a stage of remarkable camouflage. Its light brown chrysalis, speckled with dark spots, mimics the appearance of a dead leaf, blending seamlessly into its surroundings. This clever adaptation protects the butterfly during its vulnerable period of metamorphosis, showcasing the marvels of natural selection.
Adult Butterfly

Males boast pale blue wings dusted with white scales, while females may present white wings with blue bases or possess forewings with a distinct dark grey band, illustrating the diversity within the species.
Color and Appearance: With wings spread, the delicate hues and patterns of the Summer Azure come to life. The underside of the wings features a chalky white to dull grey palette, adorned with tiny grey spots and a subtle line, adding to its enchanting appearance.
