A sticky end

This week I got just a little bit fascinated by insects caught on the sticky globules on the leaves of sundews. In the first photo a small insect is caught on Drosera whittakeri - I only ever see small insects on these plants. The other photos are Drosera peltata - some quite large insects get tangled up with this beauty. I reckon there's a PhD in what types of insects get caught and why, or maybe someone's already done it. The last photo shows the leaf after it has slowly curled in around the insect in order to absorb the nutrients.
