Rhembobius abdominalis

Natural history and identification

Rhembobius abdominalis is an introduced parasitoid wasp. Cushman’s examination of museum specimens documented rearings from the narcissus bulb fly Merodon equestris in Washington and from Eumerus strigatus in California. These host records establish a relationship with bulb-feeding flies, but they are not Kauaʻi rearing records. Hawaiian checklists distinguish the introduced subspecies pacificus; its presence alone does not measure biological-control success on the island.
