Hymenoepimecis argyraphaga is a Costa Rican parasitoid wasp whose host is the spider Leucauge argyra.

[3] Its ideal habitat would include good sources of food, mating sites, and a stable population of their host spider.

While the males seem to fly in random patterns, they locate the females within minutes, suggesting a long range pheromone.

For the deceiving method, the wasp would act as if it was caught in the spiders web and lay still on its back.

[4] 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.

Even if the larva is removed prior to the web-building process, the spider still engages in aberrant web-spinning.

[3] Normal web weaving consists of several steps:[7] The modified web that the larva causes the spider to build consists of several heavily reinforced radial lines that are attached directly to the substrate; sometimes one or more frame lines or vestiges of a "temporary" spiral are also included.
