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. These spiders are shy and rarely encountered. The bite of the female black widow or northern widow spider is harmful to humans.
