First Leafcutter Bee of the Season in Vancouver: California Lilacs Bloom

A California lilac shrub stopped me in my tracks at the busy intersection of W4th and MacDonald.The flowers were covered with bees of all stripes scrambling to collect pollen. I watched as their pollen baskets filled and their jodhpurs grew fat with lemony pollen.

There were bumblebees, andrena mining bees, and lots of these solitary bees with striped butts.

Back home in our garden I also spotted the first leafcutter of the season, looking fluffy and freshly hatched. I am amazed at how having three lupins in my back yard has attracted a variety of native bees.

The wool carder bees have also set up shop at the lupins where the males patrol the flowers and mate with the females. I witnessed a male wool carder bee knock a bumblebee queen right out of the flower with a full body check. She didn't even see it coming. Cheeky!

 I also observed a honeybee try her darndest to access lupin pollen or nectar, but she gave up after two valiant attempts. These small bees are sneaking in and gathering pollen, flying under the radar of the possessive wool carder males.

As the blue orchard bees are wrapping it up, the smaller summer mason bees are getting busy. Even this little one can trip the keels of the lupins to daintily  sip the nectar.

I'm also pleased to announce my first sighting of a cuckoo be in the forget-me-nots our back yard. My friend Jasna tells me the rim around the nectar turns from yellow to white once the flower has been pollinated. Cool!

Queen and Comfrey: Visit VanDusen Gardens this Victoria Day Weekend

 If you want to visit VanDusen gardens, this is the long weekend to do it because there are so many cool plants in bloom and the bees are very busy. The laburnum walk is humming with bumblebees. This comfrey is also a popular spot for the queens and workers. It's a good place to observe different species of bumblebees working alongside each other.

We don't have many redbud trees in Vancouver, but this is a beautiful example of a Judas tree with pea-shaped blossoms that is a bumblebee favorite.

Here's a close-up of the stamens and the nectar guides. The blossoms are a striking hue of hot pink.

They're Back: Turquoise Sweat Bees Emerge in Vancouver on Mother's Day

 Happy Mother's Day! We celebrated with a picnic at the farmer's market and I spent some happy time gardening at home and at MACC. I noticed that the white Dutch clover and red clover are blooming today, which may be an indicator for the arrival of some late spring emerging bees such as this turquoise sweat bee and the common large Adrena mining bees we have here. These flowers are five spot, which reseeded themselves from last fall. There were all sorts of bees in the flowers from honeybees down to tiny black solitary bees.

The last of the blue orchard mason bees were also foraging in the five spot and the poached egg flowers, which also reseeded themselves generously.  I also witnessed a small female mason bee tripping the keels of the lupin flowers and drinking the nectar in my back yard.

I noticed that even though the two patches of flowers were side by side, the syrphid flies seemed more attracted to the yellow flowers, and the bees were more bonkers over the five spot. It would be worth doing a quick survey of these flowers every time I visit the garden.

The native roses we planted are also in bloom and they were full of little mining and sweat bees swimming in the stamens. Another phenological indicator that's about to happen is the mock orange trees are just starting to bloom.

On a completely different note, I am suddenly seeing a lot of click beetles this year. Keep an eye out for wire worms!
