Variable cracker

Variable cracker

Hamadryas feronia

A species of Crackers

The upperside of the fore wing is a mosaic pattern of white, brown and bluish-grey, with a row of small eyespots parallel with the outer margin; a small red bar occupies the discal cell. The upperside of the hind wing is similar but has few white patches and larger more distinct eyespots. The underside of the fore wing is white or whitish-tan with dark markings, a small red bar and a black submarginal eyespot, and the under hind wing is white or whitish-tan, with dark markings and blue rings containing larger eyespots near the rear margin. The larva has two colour morphs; it is either bluish-black above with brownish-white speckles and reddish spots on the side, or it is greyish-green with a pale-coloured longitudinal line on the side. It has dorsal spines on the second and third thoracic segments and on the seventh and eighth abdominal segments. The pupa has two long processes on its anterior end.

Life Cycle of Variable cracker
Egg The egg stage is the beginning of the variable cracker's life cycle. The eggs are laid by the adult in clusters or singly, often on host plants. They are tiny and vary in color, typically oval or round in shape.
Larva As larvae, variable cracker caterpillars hatch from eggs and exhibit a strong appetite. They are elongated with distinct, often colorful patterns. Growth involves several molts, with size and coloration changing as they develop.
Pupal The pupal stage sees variable cracker transforming within a chrysalis. Predominantly immobile, it undergoes significant internal changes. The chrysalis itself may be camouflaged or adorned with defensive structures.
Adult Emerging from the pupa, the adult variable cracker's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How Can You Attract Variable cracker
The adults are typically attracted to nectar from flowers. Therefore, setting up a garden with nectar-rich flowers or using artificial nectar feeders can act as a trap to attract them.
Rectangle
Habitat Preferences of Variable cracker Through Different Life Stages
Eggs of variable cracker are typically found on the host plant leaves where adult butterflies lay them. As caterpillars, they are found eating on their specific host plants, often hidden from predators. Pupae are generally attached to leaves or stems of nearby vegetation, camouflaged within the environment. Searching for variable cracker at different stages involves inspecting the undersides of leaves for eggs, searching host plants for caterpillars, and checking for pupae among foliage. Adults prefer forested areas, gardens, or places with abundant flowering plants as they feed on nectar and can be spotted around these regions during their flight.

How and Where Can You Find Variable cracker at Different Life Stages
Egg The eggs of variable cracker can be located by inspecting the leaves of their host plants. Look for small, ovular objects attached to the underside of leaves or along stems.
Larva Variable cracker caterpillars can be found by searching the host plants. They often eat leaves, so look for signs of feeding such as chewed leaves or frass (caterpillar droppings).
Pupal The chrysalises of variable cracker are typically found attached to the host plant or concealed in nearby foliage. They can camouflage so inspect the plants carefully for their distinctive shape.
Adult Adult variable cracker can be found near nectar sources such as flowering plants. They are attracted to brightly colored flowers and can often be seen feeding or basking in the sun during warmer parts of the day.

Are Variable cracker harmful to humans?

Some larvae of tortoiseshell butterflies feed on milkweed, which is a poisonous plant containing cardiac glycosides, so the larvae are poisonous. Although poisonous, these butterflies will not directly affect humans if not swallowed. Touching the larvae of certain tortoiseshell butterflies may cause a rash.
