Stick Insects eggs Dispersed by Being Eaten!

[BillTre]

Similar to how some plant seed get spread to non-local areas, a percentage ofthe eggs of stick insects can survive passage through a birds gut.

That's really interesting. Stick insects being dispersed by birds? Something that baffles me.

Plant seeds and some insects eggs/larvae survive a GI transit of (usually) a bird gut. Some actually require it as part of an organism's dispersal strategy.

Examples:
chironomid Chironomus salinarius {non-biting midge) larvae are carried passively in bird guts to new environments.
