- Cockroach (Roach)
- Drassidæ
A large family of spiders, varying greatly in shape, color, and habits. Most of them are dull colored, and live under stones, or in silk tubes on plants, and make no webs for catching insects. Their eyes are small, and arranged in two rows on the front of the head. Their feet have two claws and a bunch of flat hairs. The spinnerets are usually long enough to extend a little behind the abdomen. The figure is a Drassus, and the eyes as seen from in front. - Agalenidæ
Long-legged, brown spiders, with two spinnerets longer than the others, and extending out behind the body. Figure is Agalena nævia, the common grass spider. They make flat webs, with a funnel-shaped tube at one side, in which the spider waits. - Spiderweb
The simple nests and tubes that have been described are made by spiders, most of which spin no other webs. The larger and better known cobwebs for catching insects are made by comparatively few species. On damp mornings in summer the grass-fields are seen to be half covered with flat webs, from an inch or two to a foot in diameter, which are considered by the weatherwise as signs of a fair day. These webs remain on the grass all the time, but only become visible from a distance when the dew settles on them. Figure is a diagram of one of these nests, supposed, for convenience, to be spun between pegs instead of grass. The flat part consists of strong threads from peg to peg, crossed by finer ones, which the spider spins with the long hind-spinnerets - Stages of the Diamond-back Moth

showing proboscis formed by flexible maxillae (g) between the labial palps (p);c, face; e, eye; the structure m has been regarded as the vestige of a mandible. B. Basal part (b) of maxilla removed from head, with vestigial palp (p). Magnified. - Common Cockroach
(Blatta orientalis). a, female; b, male; c, side view of female; d, young. After Marlatt, Entom. Bull. 4, U.S. Dept. Agric. The young creature is hatched from the egg in a form closely resembling, on the whole, that of its parent, so that the term 'miniature adult' sometimes applied to it, is not inappropriate. The baby cockroach is known by its flattened body, rounded prothorax, and stiff, jointed tail-feelers or cercopods; the baby grasshopper by its strong, elongate hind-legs, adapted, like those of the adult, for vigorous leaping. - Bees on clover

Diagram illustrating the relationship between a mature plant of Herpomyces stylopygae and the integument of Blatta orientalis. Richards and Smith have studied the life history of Herpomyces stylopygae on the oriental cockroach. The plants grow only on living cockroaches, and the infection is disseminated by contact. - Bees in Clover
