How many times do beetle larvae usually molt before pupating?

Beetle larvae typically molt between three and five times before reaching maturity and entering the pupal stage. During this process, the larva feeds until its skin, or cuticle, becomes too small and splits, allowing the insect to crawl out and form a new, hardened skin. Once the larva is mature, it enters a nonfeeding prepupal stage before transitioning into the pupa.1
