Dutchman's Breeches. Just another wild variant in the dance of plant with bee. Wouldn't you like to see an evolutionary time lapse of the development of this flower as it couples in just the right way with bumblebees; one rewarded with an exchange of gametes and the other with food for it young, whilst leaving the other pollinators to lean against the gym wall.

Dieunomia heteropoda, male, note the flanges on the rear tibia

Dieunomia heteropoda, Anne Arundel County, Maryland, from a nesting aggregation in a sand pit, the only one in the state I am aware of.

A very cool find. This is a lovely male Dieunomia nevadensis. It was found in Maryland at one of the Chaney Sand Mines. They kindly scraped a section of the site and sure enough it was colonized by all sorts of cool sand bees. No sand...no sand bees. That sort of thing. This one is particularly noteworth because the nearest record was from North Carolina.

150 year old specimen from Mexico that was deposited in the Paris Entomological Collection. Note the crenulated antennae and the fact that the specimen has largely retained its shape and color all these years. Many of these old specimens are still our reference points for taxonomy, distributions, and what things were like in the past.
