How does a parasitic wasp complete its life cycle inside a caddisfly case?

To complete its life cycle inside a caddisfly case, the parasitic wasp performs the following steps:

• Host Seeking: The adult wasp actively searches for its host underwater.1
• Oviposition: Once the host is located, the wasp lays its eggs directly inside the caddisfly's protective larval case.1
• Development: The parasitic larva hatches and devours the caddisfly larva.1
• Pupation: The parasite remains within the safety of the caddisfly case to undergo pupation.1
• Emergence: After overwintering inside the case, the adult parasite emerges in the early summer to continue the cycle.1
