Erin was Right: Ground Nesting Bees at the Sunset Community Centre


One day when biologist Erin Udal and I were driving past the Sunset Community Centre on Main Erin looked at the adjacent hill and said, "I bet there are ground nesting bees there." Well of course, curiosity drew me to the hill and I did a quick search for bees. Turns our Erin was right.


This hill just north of the centre has a patchy lawn with Dutch clover and dandelions. On a muggy overcast day the weeds were full of bees. It's also located right next to the Sunset Nursery, which likely supports a few bee species in itself. The fence along the nursery hosts vetch and morning glory, more weeds for bees.


 The soil exposed in the patchy lawn is quite loose and sandy, and the angle of the hill would help with drainage, keeping the nests dry.


It's that time of the year when competition gets fierce for nectar and pollen, making leaving the flowering weeds more important than ever.


It's a pollinator party!


Bees also love these silk trees and the scent of the blossoms is heady.


A large Eastern bumblebee shows off its forked tongue while posing on a morning glory flower.


This is a great spot for a lovely beech tree.


And here's an Agapostemon, a beautiful ground nesting sweat bee, just as Erin predicted. So I'm throwing down the gauntlet: I really think the gardeners that work in the Sunset nursery could create a showcase bee garden around the base of this little hill. I'd also love to see an art piece made of natural materials that features the habitat and protects the nests from too much foot traffic. Furthermore, I'd love to see a pollinator pathway project that continues over to the skating rink grounds where there is more potential for pollinator habitat and onto the school grounds of Henderson Elementary School. From there, the beautiful front and backyard gardens would continue supporting bees on all the way to Fraser Street, making it a fantastic habitat corridor. Let's do it!

An Urgent Message: Lawn Pesticides Kill Bees!

This is an issue that makes me so emotional, I can hardly restrain myself to write coherently about it, which is why I am going to refer you to an article on the subject on the Xerces Foundation website.
Please read this article and avoid the pesticides on the list AT ALL COSTS. These pesticides accumulate in plants for up to six years and also build up in the soil. When people use them on lawns to kill European chafer beetle larvae they kill non-stinging ground nesting bees. Please spread the word. Make signs. Raise hell! Send your protest photos to me: beespeaker(at)gmail(dot)com.

Chafer Beetle Shadenfreude


As the European chafer beetles and their predators ravage lawns in East Vancouver, I am silently cheering them on. Skunks, raccoons flickers and crows are the Vancouver foodies who love the new culinary trend in raw exotic larvae. The scruffier the lawn, the more it appeals to little ground nesting bees. On a sunny day you can look at lawns like this and see masses of them digging holes and laying eggs, with cuckoo bees lurking and nipping in to lay their eggs and then shirking their maternal duties. Carnivorous wasps are foodies too, hovering above the living buffet to snatch their favorite delicacies.

Will Fire Ants Affect Native Ground Nesting Bees?


Peter did some sounds recording of bees today at VanDusen Gardens while I took photos. An area that is rich with ground-nesting bees has been invaded by fire ants. They can quickly take over an area of ground with their large nests. I hope the fire ants will not be a threat to the beautiful ground nesting bees near Alma VanDusen meadow. Ditto for the treatment to get rid of the fire ants.
