Life Cycle of Yellow-legged black
Egg In this initial phase, the yellow-legged black is a dormant, non-feeding stage. The eggs are typically oval and may vary in color, often laid in clusters or individually in a designated habitat.
Larva Following hatching, the larva of the yellow-legged black appears worm-like, with a distinct head and segmented body. The larva focuses on feeding and growth, molting several times as it increases in size.
Pupal The yellow-legged black enters the pupal stage enclosed in a puparium. This stage is a non-feeding period of drastic transformation, during which the yellow-legged black's tissues and organs are reorganized into the adult form.
Adult Emerging from the pupa, the adult yellow-legged black displays complete wings and functional reproductive organs. Its exoskeleton is fully sclerotized and pigmented, enabling flight and mating activities to ensure species continuation.

Habitat Preferences of Yellow-legged black Through Different Life Stages
Eggs of yellow-legged black are deposited in decaying organic matter, often in soil or near water sources. The larvae, which require a moist environment, are typically found in similar decaying organic materials or compost heaps. As they develop, they are more commonly seen within the soil where they continue to feed and mature. The pupal stage occurs in drier areas of soil or leaf litter, where they undergo transformation. When searching for adults, one should look near flowers and foliage in various ecosystems, such as woodlands, meadows, and gardens, where they are actively feeding and mating.
