One insect species parasitizing adults of the green lacewing Chrysopa chi Fitch and the cocoon of a second species were encountered in western Michigan. Adult females of the ectoparasitic ceratopogonid midge Forcipomyia eques (Johannsen) were found attached to the forewings of two adult hosts but the cocoon of the endoparasitic species remains unidentified. It appears to be the work of a new species or a described species not yet known to parasitize chrysopids because the cocoon is different from the only such specimen known for the euphorine braconid Chrysopophthorus americanus Mason, the only U.S. insect suspected as an internal parasite of adult chrysopids. The braconid is rarely encountered but known from Arizona and presumably occurs in other southwestern states where the solution to the identity problem might be found.
