Abstract
Summary. 1. The length of time that a gall‐forming midge, Rhopalomyia califomica, was vulnerable to attack by four parasitoid species was measured in the field at two locations.2. The midge had a restricted window of vulnerability to each of the parasitoid species, but similar windows of vulnerability were found at the two sites.3. A stage‐structured model was used to illustrate that the length of the vulnerable window should have no effect on the fraction parasitized by a single parasitoid species if that species is the only parasitoid attacking the host in a coupled host‐parasitoid interaction. However, the length of the window of vulnerability can have a positive effect on the fraction parasitized by a species in competition with other parasitoid species.4. The length of the window of vulnerability can help explain the relative field abundance of four of the common parasitoid species of R.californica.
