Abstract

We record the first occurrence in British Columbia of <i>Homalotylus californicus</i> Girault, a parasite of <i>Coccinella californica</i> larvae. Parasitized larvae are mummified and hardened with an abnormal bluish tint so they are easily recognized in the field. The rate of parasitization in the field was 13%. The significance of this and related parasites of Coccinellids is discussed.
