Zinc-Tipped Drill Helps Wasps to Lays Eggs inside Fruits

It will be really interesting to know that scientists have recorded a video that shows a parasitic wasp using a zinc-tipped drill to bore into fruit. But why it does that: actually the wasps lay their eggs inside the fruit after penetrating it with the help of a drill.

The video was captured by the Indian Institute of Science in Bangalore to show that wasps use a fruit-drilling and egg-laying tool, which is thinner than a human hair. The teeth of the tool are enriched with zinc. Findings of the study have been published in the Journal of Experimental Biology.
