hole or (in some species) replacing them with other lines 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. The reinforced lines are built using a subset of the same sequence of movements that the spider performs during the construction of frame lines in the normal web, repeated many times over. Thus the larva appears to be able to induce very specific behavioral responses in the spider. The lifecycle of the wasp was filmed for the BBC series Life in the Undergrowth (programme 4 in the series, Intimate Relations). See also Glyptapanteles, a genus of parasitoid wasp with a similar larval capacity to manipulate hosts to its own ends. Ampulex compressa, or the "emerald cockroach wasp", a wasp capable of debilitating cockroaches into serving as docile hosts for its eggs.
