During a fly's lifetime (usually a 30 day cycle), a female fly will lay anywhere from 400-600 eggs. Each fly egg hatches into a small, grub-like, creature (larvae), which looks more like an inchworm than a fly. By eating nutrients from soil, ponds or even in the sea, larvae will grow to adult fly size within a few days.
A spider web, spiderweb, spider's web, or cobweb is a device created by a spider out of proteinaceous spider silk extruded from its spinnerets. Spider webs have existed for at least 100 million years, as witnessed in a rare find of Early Cretaceous amber. Insects can get trapped in spider webs, providing nutrition to the spider; however, not all spiders build webs to catch prey, and some do not build webs at all.
