- Description:
- The eggs are laid in a pond, which the larvæ subsequently inhabit. These are mobile and predacious, propelling themselves by ejecting water, and a favourite position is hanging to a floating stem. When fully developed they emerge and climb up the folded leaves of the water lily; they take a firm grip of the edges. When a larva is quite dry the case splits over the back, and through this opening the fly works its way. A few hours hanging in the air hardens the wings and the first flight takes place. Note the large lateral projecting eyes, the thick upper lip, covering a mouth capable of demolishing even a butterfly; the beautifully reticulated wings, and the forceps at the end of the body.
