Meshweb weavers

Nigma walckenaeri

Green meshweaver

This spider's abdomen shines such a bright metallic green that it can look like a drop of dew rather than a living animal resting on a leaf.

The Green meshweaver is the largest species in its family, with a yellowish body and legs and a strikingly shiny green abdomen that makes it easy to pick out among duller relatives. It rests on the upper surface of broad leaves such as ivy or grapevine rather than hiding away.

It spins a small sheet web across a leaf and waits at the edge, rushing out to seize insects that land on the silk, sometimes prey larger than itself. Females hide their egg sacs away from the retreat, often some distance from where they hunt.
