Keywords:Diptera, <i>Dasyhelea oppressa</i>, Ceratopogonidae, <i>Mycetobia divergens</i>, Anisopodidae
AbstractLarvae and pupae of <i>Dasyhelea oppressa</i> Thomsen and <i>Mycetobia divergens</i> Walker were found in the sap on the ulcerated trunk of a horse-chestnut tree in Vancouver, B.C. Adults of both species were reared from these collections. This record is the first for <i>D. oppressa</i> west of Manitoba in Canada and Iowa in the United States and for <i>M. divergens</i> the first record west of Alberta and Arizona.
