Hesler, Louis S., Beckendorf, Eric A., Martens, Abigail P. & Johnson, Paul J., 2023, A new state record of Eucera (Xenoglossa) kansensis (Hymenoptera: Apidae) in South Dakota, USA, Insecta Mundi 2023 (985), pp. 1-6 : 3-4

Eucera (Xenoglossa) kansensis (Cockerell, 1905) ( Hymenoptera : Apidae )

We recorded a total of 88 specimens of E. kansensis (61 females, 27 males) from South Dakota in our survey. Eucera kansensis was collected in a wide variety of habitats at the ESDSWRF, NCARL, Aurora prairie, and the remnant prairie at the Round Lake Game Production Area, but not at the Arlington prairie. The earliest date for the new state record consists of two specimens both sampled by unspecified method at the ESDSWRF on 21 August 2013. Additional specimens were collected in blue vane traps from 2019-2021. No further records of E. kansensis from South Dakota were found in records from SCAN (2022) or iNaturalist (2022).

Eucera kansensis was collected as early as June 23 (2021) and between August 13 and August 27 (2019). Thus, the records indicate that E. kansensis is flight active generally from late June through much of August in eastern South Dakota.
