Psechridae is a family of araneomorph spiders with about 70 species in two genera. [1] [2] These are among the biggest cribellate spiders with body lengths up to 2 centimetres (0.79 in) and funnel webs more than 1 metre (3 ft 3 in) in diameter.
At the beginning of this activity, a word is stated and given in a sentence. The user must then guide a tiny spider over a spider's web but it crawls over the letter-shaped bugs that correctly spell that word.

The Agelenidae are a large family of spiders in the suborder Araneomorphae.Well-known examples include the common "grass spiders" of the genus Agelenopsis.Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (Eratigena agrestis) may be medically significant, and some evidence suggests it might cause necrotic lesions, [1] but the matter remains subject to debate.

Erigoninae are the most numerous of the sheet weavers, with more than 2,000 described species. Many species live in leaf litter and build minute sheet webs. [1] These spiders probably are more important as members of the beneficial complex of predators in agroecosystems than is generally known. [2]
