Which spider is known for the largest egg sac relative to its body size?

Quick Answer

Some orb-weaving spiders produce very large egg sacs compared with their bodies, but the exact record can vary by species and measurement method.

The Full Story

Many spiders invest heavily in egg sacs, and some orb-weavers are especially notable for the size of their silk-wrapped egg cases relative to their own bodies. These sacs protect developing spiderlings from predators and environmental stress. Because spider species differ greatly in body size and reproductive strategy, no single universal record is always used. Still, large egg sacs are a striking feature of several web-building spiders.
