Common Crow
Euploea coreAlso known as Common Indian Crow, Australian Crow, Oleander Butterfly
Common crows display velvety deep brown wings lined with crisp white marginal spots and flutter with a slow, unhurried flight pattern. Their bodies sequester plant toxins during the caterpillar stage, rendering adults unpalatable to birds and allowing them to glide openly in bright sunlight. Females lay ribbed eggs on poisonous host plants like oleander and milkweeds, ensuring the next generation inherits the same chemical defenses.
