A species of Sphecodes captured in agriculture areas of Puerto Rico by Sara Prado. This is either a new island record or a new species as there are no known records for Sphecodes for the island. Notice the lovely WIPs (Wing Interference Patterns)

An odd story of invasion. This is a Sphecodes, we have posted a series of them recently on Flickr. They are nest parasites. They gather no pollen themselves. There are many species...the odd thing is that I found this on Maui in the Hawaiian Islands. The only native bees on the island (discounting some maybe native bees) are masked bee from the genus Hylaeus.

An unknown species of Sphecodes collected by Tim McMahon in Cecil County. Interesting to ask why Sphecodes often have bring red abdomens when bees theoretically can't see red. Photographed by Brooke Alexander

Triepeolus concavus. Most Triepeolus bees are nest parasites of Melissodes, but a few interestingly have taken up with other groups of bees. This big one invades the nests of Svastra species...a group allied with Melissodes but a bit more robust and buff in their body. This one collected in Badlands National Park.

New species for the state of Maryland, this is Triepeolus concavus. As are all Triepeolus this one is a nest parasites. In this case, it's host is Svastra obliqua, an uncommon bee that loves large composites and is a good indication of high-quality habitat.

Triepeolus cressonii, a couple of additional shots of this new "state" record for Washington DC. The specimen was collected at Kenilworth Aquatic Gardens along the Anacostia River by Chelsey Nordstrom, who also took the picture.

A new Washington DC record, Triepeolus cressonii, captured in the Kenilworth aquatic Gardens along the Anacostia River. A very urban landscape, but one that still retains quite a bit of original nature thanks to the work of the National Park Service maintains the property as well as adjacent areas along this quiet backwater.

Triepeolus distinctus. This is the female of the male of the species that was posted a couple of weeks ago. Equally lovely. Both were found in an untended sand pit near my house. The key is untended as most sand pits not are filled with junk and the capped with clay and then planted with cool-season grasses and maybe some trees. The worst thing you could do.

Red-eyed Bee. What a lovely palette this bee has of tomato saturated reds, on a shiny black integument with stripes of appressed off-white hairs. This bee was found when Mimi Jenkins and I went to my favorite sand pit to collect bees while our offices were shut down due to a security threat. Such a bonus.
