Nomada kohli is a brood parasite of other bees, and Lasioglossum puncticolle is probably the host (Stoeckhert 1919, Schmiedeknecht 1930, Standfuss and Schwarz 2007). The species is bivoltine, in that it has two generations per year, and the flight period is from the end of April to the end of June, and from the end of July to the end of August

It inhabits dry open grasslands, vineyards, dykes, verges and river banks (J. Smit pers. obs. 2013).
