Moths identified as adults of the blackheaded fireworm of cranberry, Rhopovbota naevna (Hbn.), were obtained from larvae that were very destructive to the "evergreen heckle berry," Vaccinium ovalum, Pursh., on the Olympic Peninsula in Washington in 1958 and 1959. These larvae are known locally as "tipworms" from their habit of feeding on the terminal growth of the young shoots of the host plant. The "evergreen huckleberry" is a new host for host for the blackheaded fireworm in America. Previously it was known only from cranberry. Two parasitic insects were reared from, the "tipworms," an ichncumonid wasp, Horogenes sp., and a tachinid fly, Eulasoniasp. Both are now records. The parasitic wasps killed the "tipworms" in the last larval stage and destroyed about 10% of them. The synonomy of the blackheaded fireworm is questioned and reasons for this uncertainty are given.
