Bolas Spider Moth Mimic

An Australian moth whose eggs are so tough they resemble seeds and can survive passage through a bird digestive tract — potentially allowing bird-mediated dispersal over long distances.

💡

Did You Know?

The eggs of this moth are so hard-shelled they can survive being eaten by a bird and pass through its digestive system intact — a unique form of insect dispersal.

Grass Webworm Moth

A small brownish moth with faint wavy lines across the forewings. Its larvae spin silk webs over grass and can cause serious damage to tropical lawns and pastures.

💡

Did You Know?

Larvae create silken tunnels at the base of grass stems where they hide during the day.
