Spider Season is Upon Us – A Guide to Spiders of Indiana

Fall is here, and so are the spiders. We’ve had an increase of calls and questions about the increase of spider population this year. We’d like to take the time out to drop a little knowledge about these eight-legged guys and why they’re larger in numbers this season. Below is some great info on our local spider population from spiderid.com.

(Grass Spiders)

Summary – “Grass Spiders” are represented by 13 species collectively found throughout most of the U.S. and southern Canada, and northern Mexico. Like all members of the funnel weaver family Agelenidae, they spin dense, non-sticky, sheet-like webs with a funnel-like retreat where the spider hides.

Araneus diadematus

(Cross Orbweaver)

Summary – This spider is named for the pattern of white spots on the abdomen that form a cross in most specimens. Native to Europe, it was introduced to North America long ago. It spins the classic wheel-like orb web, usually sitting head-down in the hub (center), at night as well as during the day.

Amaurobius ferox
(Hacklemesh Weaver)

Summary –  Native to Europe, it has become established in southeastern Canada and the eastern U.S., though is not limited to those regions. This robust spider is common in and around homes, but also lives under rocks, logs, in leaf litter, and other dark, humid places. Adult males are notorious for wandering in the spring.


Argiope aurantia
(Black and Yellow Garden Spider)

Summary – Mature females are enormous, their bold black-and-yellow pattern adding to their intimidating appearance. Common in gardens, orchards, forest edges, old fields, and farms, they spin a classic round orb web which is usually decorated with a bold, zigzag band of silk called a stabilimentum.
