and continuously sting for 2 minutes. Once the host is paralyzed, the wasp has 5-10 minutes until the paralysis wears off. The wasp will then use the ovipositor to probe for existing eggs or larvae in the spider, and if she finds any, she will remove them to replace with her own egg. The egg is glued to the abdomen of the spider. 2-3 days later the first-instar larva will hatch, and partially emerge from the egg. The first instar will create a large hole in the spider's abdomen in order to access the hemolymph. The larva will then feed on the hemolymph, creating a hardened saddle. During this time, the spider goes on about its normal web building and insect-catching behavior for the next one to two weeks. In another 2-3 days the second-instar larva will hatch and insert its hook-like structure into the hemolymph saddle and completely emerges from its egg. When the larva is ready to pupate, it releases a chemical induction that causes the host to spin a special web to make a cocoon for the larva, the design of which is completely different from any it has ever made, and then to sit motionless in the middle of this web. Even if the larva is removed prior to the web-building process, the spider still engages in aberrant web-spinning. Once the cocoon has been made the larva will kill its host and pupate. Seven days later metamorphosis happens and the wasp will live for 2-3 weeks. Behavior alterations of Plesiometa argyra Normal web weaving consists of several steps: Build non-sticky frame lines attached to supporting objects and a few initial radial lines. This process sometimes involves establishing connections with surrounding objects by floating a line in the wind and hoping it catches somewhere. Add more non-sticky radial lines attached to these frame lines, in some cases adding at the same time less peripheral, "secondary" frame lines. Add several tight loops of non-sticky silk at the hub of the web. Lay a loose "temporary" spiral of non-sticky silk, starting near the hub and ending near the edge of the web with about five times the spacing of the final sticky silk. Draw the tight spiral of sticky silk starting at the edge of the web and working inward, and removing during the same process the loose spiral. Remove lines at the center of the hub, leaving a
