A series of pictures of a male and female species that loves Bellflowers (Campanula). Meaning that the female of this species provisions its nest (note: males never help in all Hymenoptera) with the pollen of this plant.

Chelostoma rapunculi. Invader from Europe. Mostly occurring in the Canada/U.S. border and loves introduced bellworts. We have other pictures of this species, but here is an undercarriage view of the abdomen with all the male options in view. Those crazy insects have come up with a completely different mating system and creates lots of complexity in the males.

Chiasmognathus c.f. gussakovskii, Cross Mandibled Bee, specimen collected by Wojciech Pulawksi in TajikistanVery small bees have very small nest parasites.

If you were in the Badlands of South Dakota in the Summer, and were paying attention to your bumblebees, you would see this one. Bombus nevadensis. It is big and the queens are extra beefy. This is one of the dark bumbles. More black on the sides of the body and tinted wings.

For some reason I have not put up a Bombus perplexus shot yet. Here is one that Wayne Boo did a couple of years ago and I am just now getting around to shopping. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200.

More Bombus perplexus shots, in this case...males. You can tell they are males because they have 13 rather than 12 antennal segments and the hind legs lack the pollen carrying corbicula (bare area) on the tibia. Lemon yellow though! Specimens from Central Pennyslvania from Laura Russo's study there. Photographs by Kelly Graninger.

Sections of a male Bombus perplexus, illustrating the hair and shape patterns. A regular, but somewhat uncommon bumble bee, that is noted for the more extensive yellow hairs on the thorax and abdomen than most bumble bee species. Photographs by Greta Forbes.

Let us present the first record of Bombus rufocinctus for the state of Pennsylvania. This is a not uncommon northern and western species....it just hasn't been found in PA as of yet. Some notes on its identification.

This is the main orange butted Bumblebee of the East. Bombus ternarius. It can be very common in places like the Adirondacks where this one was collected, but occurs throughout a wide range of the Upper Midwest to New England and throughout southern Quebec and Ontario in our gardens and fields.

Bombus terrestris - A domesticated bee. Widely used in agriculture in green house pollination as well as in the field. Also one that has been introduced into several parts of the world... Causing major problems in South America where some combination of competition and disease harms the native bumble bees.

One of the species of bumble bees that have declined since the introduction of the pathogen Nosema bombi, but there are some suggestions that populations have managed to survive or increase a bit ,,,this one, captured by Laura Russo is at the southern edge of its range and a good sign for retention.

More from last year's expedition to Chile with Laurence Packer. Such a lovely country...we camped in a new place every day. Ping ponging from the Andes to the Coast sleeping along the road or in open pastures. Lovely people, easy travel, no problems with law enforcement people. This is a Caenohalictus species of some kind.

As the name implies this species from East of the Andes superficially resembles the parasitic bee genus Nomada. However for whatever reason they have chosen from the wardrobe of bee colors the same cloths they act quite differently. Of note is that both the males and females of this species gather oil in addition to the usual pollen and nectar.

Now this is a rare bee, I have never seen or collected this species before seeing this lovely male in Kassie Urban-Mead's collection of bees from Connecticut, she collected it last year in a field on Verbena, there are only a scattering of records from NJ to Connecticut representing a disjunct population from the populations occurring in the western prairies, perhap

Wayyyyyy up in the Andes spitting distance from Argentina, this wee Callonychium chilense was collected on an expedition with Laurence Packer to southern Chile. One of those one way dirt roads that hugs the mountains and gives one opportunity to fall into the valley in a truly spectacular way. Memorable.

Southern South America is where you will find this as yet another group of relatively little studied bees. This one collected in Peru by the Packer lab and has some nice Wing Interference Pop.
