Other Spiders (tig. 406, c) are indeed able to i-im quickly, but they render the task of catching prey easier by making webs and nets, on which they move about with great dexterity, while other animals, especially insects, become very easily entangled. The webs them- selves are of various kinds, and constructed with more or less skill ; a 406. Salticun scenic/is Thomigus citreus Tfg>iearia Jnuirstica Q they are either delicate and thin and formed of irregularly arranged threads, or they are of a felt-like qiiality and extended horizontally ; or again, they may have the form of vertically placed wheel-shaped nets ; in this case they consist of concentric and radial threads, which are arranged with wonderful regularity, the radial threads meeting in a central point. Tubular or funnel-shaped hiding-places for the spider are often found near the webs. Most spiders rest in the daytime, and go out for prey in the dusk or in the night-time. Many vagrant spiders, however, hunt in the day-time, even when the sun is shining.
