Funnel Web Spiders
A unique web is characteristic of this group of spiders and is more often noticed than the spider itself. The web is sheetlike, usually positioned horizontally, with a funnel leading downward to a shelter (a rock crevice or dense vegetation). Though it is often smaller, the sheet may be up to 3 feet wide and the funnel portion over a foot long.
Funnel web spiders have a pair of broad, dark, brownish bands running lengthwise adjacent to a lighter middle band on the lightly haired and roundish carapace. The legs are cream and dark yellowish brown. The abdomen is oblong, brown, with a broad, reddish-brown, zigzag stripe with a cream-colored border on both sides. The spinnerets are noticeably long.
Two species of funnel weavers are found in Missouri, Agelenopsis naevia and A. pennsylvanica. Although the former is usually larger and darker, their similar color patterns make them difficult to distinguish.
