      I'm not of aware of any  references focussing on Brassicaceae specialists but for North America, you might try A. R. Moldenke 1979 "Host-plant coevolution and the diversity of bees in relation to the flora of North America" Phytologia 43:357-419.  It lacks a little something in rigor and some of the systematics are out of date but it is a useful starting point for those interested in host plant relationships of North American bees.  Otherwise, one might check the original systematic literature.  North American Brassicaceae specialists occur in Andrena (subgenera Holandrena, Leucandrena, Rhaphandrena, Scaphandrena and perhaps Melandrena) as well as Calliopsis (Micronomadopsis), Perdita (Perdita) - several species groups and Dufourea.  I'm don't believe there are any Cardamine specialists in the North American fauna.

      Dear Colleagues:

      Drs. M. Arduser, Retha Meier and I are completing a three-year study on the pollination of the threatened wildflower, Physaria filiforme (Missouri bladderpod).  It is restricted to calcareous glades.  Plants at our site were well attended by bees but none of the 35 native species (caught over three seasons) are regarded as oligolectic on Physaria (Lesquerella) or on any member of the mustard-cabbage family (Brassicaceae) .  Could someone recommend one or more references on North American bees oligolectic on the Brassicaceae?  Correct me if I'm wrong but aren't there some andrenids oligolectic on Cardamine?
