Gynandromorph records of Melissodes trinodis and Melissodes communis (Hymenoptera, Apidae) from North Dakota, USA

Bees that express both male and female characteristics are known as gynandromorphs. Here we report and describe two specimens that represent the first documented gynandromorphs of Melissodes trinodis Robertson and one specimen of Melissodes communis Cresson (Hymenoptera: Apidae) that represents only the second known case. All three specimens were collected in North Dakota, USA and exhibit a mosaic pattern of gynandromorphy.
