- Q: i want to go to school and learn to operate over head cranes
- No. they can't chew human beings. The lengthy pointy bit on the lower back isn't a sting both. it truly is an ovipositor, designed to allow the Crane fly to position her eggs in the soil. The eggs hatch out into leather-depending Jackets, gray grubs who devour the roots of grass. once you spot starlings and different birds on a backyard poking bout into the floor, it truly is what they're searching for, effective tasty leather-depending Jackets. leather-depending Jackets make the grass of a backyard pass yellow, and die. they're pests, notwithstanding the Crane fly is purely tense even as it comes interior.
