Southern House Spider
Also known as the southern crevice spider, the Kukulcania hibernalis is found throughout the American South. Their webs may be located in dark locations indoors. Outside, they are found under logs and within trees. This species is famous for dimorphism, with males and females exhibiting marked physical differences.
Females appear gray with conspicuous patches, while males are brown or khaki in color. Females are also nearly twice as large as males and can measure up to 19 millimeters in length. Male southern house spiders have longer legs than their female counterparts, which in turn have larger abdomens. Females may live up to eight years, while the life span of the male spider is considerably shorter.
Most visible southern house spiders are male. Females are reclusive and spend their time spinning webs in secluded areas. The webs of southern house spiders are not adhesive; females must comb the strands of their webs into a mesh in order to trap insects. Male southern house spiders do not spin webs.
Male southern house spiders may resemble brown recluse spiders. However, the violin marking of the male southern house spider is narrower than that of the brown recluse and recluses are smaller in size. Furthermore, the southern house spider has eight eyes, while the brown recluse possesses only six. Unlike the brown recluse, southern house spiders administer harmless bites.
