In soutliem Europe C. conica can be confused with tlie very simi- lar C. sierrae Simon (Figs. 30-33) and C. algerica Simon (Figs. 34-37). The males of these also have two macrosetae on the fourth coxa. Natural Histonj. The orb of C. conica is found on shiaibs and understory of conifer- ous forests, sometimes deciduous, where it is the most common orb-weaver. According to Kaston (1948) the orb is wider than liigh, with 40 to 50 radii, and lacks a retreat, tlie spider resting in tlie center (Plate 1). When disturbed the spider shakes the web or may drop out of the web. There may or may not be a stabilimentum in webs of the same individual. Objects falling into tlie web and insect remains are incoi^porated into the stabilimentum. Matiue males do not build orbs. The three to five egg-sacs of loose silk are elliptical, yello\vish brown, 3x7 mm, and are attached to dead twigs or under leaves, but not to the orb. The egg- sacs contain 10 to 130 eggs (Kaston, 1948). Males are mature from May to July in.
