When do spiders lay eggs? The answer to this question depends greatly on climate and the species of spider in question. Spiders reproduce year round in tropical regions. North American spiders can breed in the spring, summer, or fall, or all three seasons. Typically, spiders in the U.S. and Canada appear more abundant in autumn because most of the large orb weavers reach adulthood at that time, and as the foliage falls from trees their webs become ever more obvious.
