Official UPSC Answer KeyUPSC Prelims 2008 • Science and Technology

Correct Answer: Option (C) — Spider

Concept & Option Breakdown

Standard Reference Verified

Sexual cannibalism, where the female attacks and consumes the male during or immediately after copulation, is a well-documented phenomenon in certain arachnid species (such as the black widow spider, Latrodectus, and the Australian redback spider). In honeybees, the male (drone) dies after mating due to rupture of his endophallus, not because the queen actively kills and eats him.

Elimination Heuristic & Exam Approach

Sexual cannibalism is most famously associated with spiders and praying mantises.
