native bees 101

Glorious wildflower meadow - a real field day!

Glorious wildflower meadow – a real field day!

Just returned from a fantastic week of bees and flowers and study and wine touring in the stunning interior of B.C. What an enriching experience it was to peer at bees in the lab, to learn more about our native bee species and then to go out into the field (literally) amidst the flowers that are the nutritional resources for the bees. (Ahem, the wine touring was not part of the course).

Our native bee ID course was led by super-star bee expert, Lincoln Best. We were at Thompson River University in sunny Kamloops; hosted by the Master Gardener’s Association and organized by master gardener and artist, Elaine Sedgmen.

I must say that one of the funniest highlights of our course was watching our fearless instructor, Lincoln Best, demonstrate how to “tumble dry” bees in preparation for pinning. Fluffing up wet bee fuzz is hard work! And listening to him describe how he had to shave the hair off a tiny bee’s face in order to find those oh-so-important identifiers, the “subantennal sutures,” was hilarious! Yup, that must have been one tiny razor!

Just a few of the stars I had the pleasure of photographing:

Andrena-on-gumweed

A bee from the Andrenidae family (I think) with a super load of golden pollen she collected from gumweed (Grindelia).

Andrena-on-gumweed-2

The thrill for me is always seeing how different bees collect pollen. This little bee has pollen right up into her armpits, all along her hind legs and even some on her abdomen.

Lori-at-the-Knudsford-Meadow-copy

Madame Beespeaker aka Lori Weidenhammer of “Victory Gardens for Bees” fame, glorying in the bee search amidst the vast, stunningingly beautiful meadow  near Kamloops. The afternoon was astounding – payne’s grey menacing clouds and gold and siena fields. Unforgettable!

male-megachididae-on-Mariposa-lilly

A very wet male bee from the Megachilidae family, waiting to dry out on the lovely petals of a Mariposa Lily. He’s got highly specialized front legs that he uses to cover the female bee’s eyes during mating. Kinky, blind-folded sex; who would have thought it?

Melissodes-and-aphid-Copperhead

A long-horned male bee (a Melissodes from the Apidae family, I think), and an aphid in discussion on a gumweed blossom. Hmmm, was the topic climate change or the vintage of nectar?

Bombus-huntii-on-gumweed

Perched on its forelegs and midlegs, a brilliantly striped bombus huntii (again, I think) purveys the surrounding territory.

Bombus-huntii-on-Melilotis

Another bombus huntii foraging on Melilotis. Look at those beautiful orange pollen loads!

bombus-on-chicory-2-at-Old-Grist-Mill

Bumblebee (possibly bombus bifarius?) deep into the nectar of chicory, and already powdered with the off-white pollen from the anthers.

Andrena-sp-on-cinquefoil-at-Old-Grist

A mining bee busily foraging on potentilla.

bombus-and-mining-bee-on-veronica-at-Summerland

The Veronica buffet – speedwell is a favorite of many different types of bees. Here, a large bumble bee and a smaller mining bee enjoy the sweet nectar.

Leaf-cutter-on-Trefoil

A leaf-cutter bee with some orange pollen on her abdomen sinks her head into the throat of a Trefoil blossom.

honey-bee-on-chicory-at-Old-Grist-Mill

Honey bee with amazing pollen loads she collected from chicory blossoms. How can she fly with such a heavy weight to carry?

Mystery-bombus-on-solidago-2

A rather blurry shot of a mystery bumble bee on solidago. More bee ID work needed here!

Bombus-on-spirea-with-rainbow-pollen-loads

This bumble bee foraging on spirea has a stunning two-toned pollen load

bombus-on-vetch-with-rainbow-pollen-load

Look at this amazing multicolored pollen load on this Bombus vosnesenskii! She’s got her head deep into a vetch blossom.

 

 

Nevadensis-queen-butt

My all-time favorite newly recognized bee was this stunningly gorgeous bombus nevadensis queen I discovered foraging on thistle. She was huge!  I’ve used an image of her as the header to my blog site.




 

a beeessential plant

I’m loving the pollen collecting and because the season is short and there are a lot of flowers in bloom almost at the same time, my days quite literally fly by.  250,000 flowering plant species on this planet, and with only about 150 samples of pollen collected to date, that’s a miniscule dent in the grander scheme of pollen, eh? In all earnestness, my goal is not the 250,000, but the exploration of the flowers that are/might be useful forage resources for our native bee species.

Basically, each flower/plant requires some research – information about its flowering period, what pollinators visit, the structure of the flower; its pollen grain form and color; the food resources the plant offers: pollen, nectar, floral oils, wax, nest-building material etc.; and what the experts say about the plant.

Here’s a page of rough sketches and info. on Sneezeweed (Helenium autumnale). I learn something new with each plant that I collect and dissect. Sneezeweed is in the Aster family. The blossom is actually composed of two kinds of  flowers called florets: the larger, outer ring of flowers, called ray florets, and the inner head, composed of fertile, bisexual (containing both male and female parts) disc florets The pollen grain (bottom right of page) is very cool – it’s covered in spikes, like a burred seed pod, and perhaps the spikes help the pollen to stick to the body of a pollinator, just like a spiky seed does?

Sneezeweed offers both pollen and nectar to visiting bees, and it also provides a good landing platform for pollinators to stand on as they work their way through the numerous, closely packed tiny disc florets. Lori Weidenhammer, in her new book, Victory Gardens for Bees, considers it a bee-garden essential plant not only because it offers good resources for bees during the high season, but more importantly, it is a much-needed pollen and nectar source later on when resources are scarce. A bee-utiful flower with beautiful golden orange pollen!

I’ll either photograph or scan the flower that I’m working on, as a further means of documentation. Below is one of my new “try-outs” in terms of producing a body of work based upon the flower/pollen research I’m engaged in presently. In this case, I’ve scanned the sneezeweed blossom. I love the way the petals look like wings, or a flouncy skirt. I’ve printed this on a translucent gampi paper, in archival pigment ink. I’ve also added the pollen color in a band, to the bottom of the image. The medium is powdery soft pastel, the same medium I’ve been using to document pollen colors these past 3 years. I like the thinness and delicate quality of the gampi – it feels ephemeral, like the flower that sit on its surface.
