Egg The eggs of berberomeloe majalis are typically laid in concealed locations near food sources. They are small and discreet, designed to avoid detection and predation.
Larva Upon hatching, berberomeloe majalis presents a triungulin stage, where larvae are active and mobile with well-developed legs, seeking out hosts to parasitize.
After the triungulin stage, berberomeloe majalis enters the caraboid larval stage, resembling ground beetles, and it becomes less mobile, focusing on feeding and growth.
Berberomeloe majalis then transforms into a scarabaeiform larva, with a C-shaped and grub-like appearance. The larva continues feeding voraciously, often underground.
Further developing, berberomeloe majalis becomes a coarctate larva, encapsulating itself within a protective hardened cuticle, reducing activity significantly as it prepares for the next phase.
Pupal Within the pupa, berberomeloe majalis undergoes dramatic transformation, rearranging its body structure to assume adult morphology. It is a non-feeding stage marked by significant physiological changes.
Adult Emerging from the pupa, the adult berberomeloe majalis displays a striking color contrast. Unlike its larvae, it has a robust body, functional wings, and is sexually mature, prioritizing mating and laying eggs.
