While developing into adults, spiders molt from 4 to 12 times. Spiders can overwinter in any stage of their development. The most recognized special skill of the spider is its ability to make a web. This is done by silk-spinning glands that are on the tip of its abdomen. The silk hardens on contact with the air.
Spiders make silk webs as snares to catch prey and to hold egg sacs.
They also use silk lines to travel long distances through the air. Spiders grow through an incomplete metamorphosis. The hatchlings look like the adult in miniature. Gradually, they grow through several molts to their mature size. The black widow and the brown recluse spiders are the only poisonous spiders found in Ohio.
