Darkling Beetle Life Cycle Stages & Development Timeline #3056546 (License: Personal Use)

This educational image illustrates the full holometabolous development of a darkling beetle (Tenebrionidae), highlighting each morphological stage: a smooth, oval egg; a segmented, yellowish larva; a pale, immobile pupa; and a glossy black adult beetle with hardened elytra. Each stage is labeled with its typical duration, emphasizing the rapid growth-especially during the larval phase-and the total ~80-day maturation period from egg to reproductive adult.

Used in biology textbooks, entomology websites, classroom presentations, and pest management resources to teach insect development, metamorphosis, or beetle identification. Matches user intent for learning about insect life cycles, especially for school projects or agricultural education.
