The Stilleto Fly


I have reached a point of insect nerdery from which there is no return: sifting through photos of flies to identify what I have photographed. It's not even a flipping bee! It's a FLY! Anyway, it was acting like a bee and dressed like the men in black suits, so I'm thinking it's a stilleto fly from the family Therevidae. The larvae are vicious and voracious, garnering the mafia-related name. They prey on the larvae and pupae of other insects. The adults feed on nectar, honeydew and pollen and occasionally on animal or vegetable secretions. OMG that sounds creepy.


 I'm pretty sure I saw another one today in some sandy soil in VanDusen Gardens, so this must be their favorite time of the year. Anyway, it's a predatory fly: enjoy!

Strawflowers and Dandelions at UBC Farm


I was talking to some permaculture students at UBC Farm yesterday and someone asked a very good question. "As cities ban pesticides, are they actually better places to raise bees than in agricultural areas?" In terms of biodiversity, cities do have areas that are good forage for a variety of native bees as well as imported honeybees. In fact, I just found a study done in 2004 evaluating bee habitat in Vancouver: Bee Diversity and abundance in an urban setting by Thomassi, Miro, Higo and Winston.  It is an excellent read.

One of the flowers that the researches found supported the highest diversity of bees was the lowly dandelion (Taraxacum officinales). As I walked around UBC Farm yesterday, I did find that this plant was the one that I observed supported the sweat and mining bees as well as the honey and bumble bees. In spite of all those fancy flowers grown for weddings and other occasions, the dandelion took home the prize for best in diversity. The false dandelion came in on top as well, as did a flower I never expected to advocate as a bee plant--the straw flower.

 Straw flowers are much loved by fall floral arrangers because of the variety bright colors and the fact that they retain their colors when they dry. The petals are papery and dry just like straw. Now when I see pink flowers like this I expect the flower to be a butterfly plant, but that big lush pad of pollen in the middle obviously makes several insects quite happy.



The wasps were more interested in little insects that might be hiding between the petals of the plant.


 There's got to be some nectar in there as this skipper appears to be filling up the tank, so to speak.


 This photo shows a photo of a honeybee next to a syphid fly so you can compare and contrast.


Here is another illustration of frilly flowers that have been bred so that there is no pollen--the Teddy Bear Sunflower.


The students spotted this bumble bee queen on one of the fluffy sunflowers and I thought she was sipping, but she was grooming. You can see here her tongue is retracted. She's not feeding on this plant, just using it as furniture, which is about all its good for.

New Bee on the Block


 I've been chasing her for three days: the elusive "I'm not a Vosnesenskii" queen. I first saw her at the back of my neighbor Jean's house in the fennel, but she evaded me. I saw her again yesterday across the street in the tall coneflowers at Kelly's house, but she flew off before I could even get the camera out of its pocket. Today I finally found her in Jean's oregano (or is it marjorum?).


She has a beautiful velvety black abdomen, with very little yellow at the top. She's got black fur around her compound eyes, and a kind of blonde mohawk with its dark roots showing.


 Then when I got home I realized I'd shot a photo of one of her (smaller) daughters at the goldenrod in Catherine's yard. The garden has a corner with blackberries, goldenrod and buddleia which is currently a very popular bee spot.


When I looked closely at this boy covered in pollen, I suspect it may be of the same nest. Now for identification. It sort of looks like Brown-belted Bumble Bee, one of the 35 species native to British Columbia. You can see a fabulous photo here on E-Fauna. But then I found a site I've never seen before called Bee Spotter and I'm looking at the Bombus impatiens or Common Eastern Bumblebee and I have a queasy feeling, this is what I might be seeing. What do you think? Is it an escapee from a greenhouse or a local yokel?

This post is dedicated to Jean's father Tony who left us three days ago, about the same time I started seeing this mystery bee.

All Petticoats and No Pollen


 I have to admit I don't know much about zinnias, but I grew some from seed this year because I read that the red ones attracted hummingbirds. I did see a hummingbird swoop down and take a sip, but they haven't exactly been a big success. Maybe one needs a critical mass of them.

Now see this zinnia is pretty enough for a Victorian seed catalogue illustration, but where's the nectar? Where's the pollen? Were Victorian plant breeders a bit too obsessed with the erotica of petticoats?


Now here's a zinnia with substance.  The bumblebees systematically go round in circles sipping the nectar in these flowers with a single row of petals.


And here's a compromise--still lots of petals, but some pollen and nectar. Now these flowers change as they mature, and I can't tell you if some of these petals fall off to reveal more florets, so I'll have to watch mine and see what develops.




 These zinnias are all in a garden plot at 16 Oaks Community Garden and they do brighten up a grey August afternoon.



Hello little ladybug larva!


Look at this amazing crop of goji berries! I am so jealous. These would be great in a bee hedgerow.




 This is one of the West Coast seeds wildflower mix--I can see them all over town. The ones with less corn poppies seem to fare better. I wish each variety was in its own little seed packet, but it's great to see these little wildflower patches here and there all over Vancouver.

Curioser and curioser!


 Can you believe the color of these tomatoes?!

Strategies for Keeping Children Calm around Bees

Sweat bee in a native plant called Pearly Everlasting. This is one of those flowers that has dry petals you can use in flower arrangements


It's a muggy hot afternoon in August. I have come to the Cedar Cottage Neighborhood House to do a bee safari with a group of 6-8 year olds. I arrive early to assess the situation and see if there are any bee plants in the immediate vicinity. The older kids are rounded up for a game involving a ball and chalk squares drawn on the ground. One of the boys is declared out and he seems upset. He goes and sits down on a log and quietly starts to sob. I go over to him and quietly tell him to take a deep breath and murmur encouragement. Then I leave him alone. The game is going on, with rules that puzzle me. I'm not the only one as other kids get frustrated and tempers flare. Another boy stops and lies down on the chalk square. He begins to cry. To my amazement I realize he is the identical twin of the first boy who succumbed to the heat. I try to calm him and hand him some lemon balm, but he pushes it away.


Okay, I've got a bunch of kids I don't know, who are overheated and volatile and we're going to be around stinging insects. This sounds like fun. To my delight there are all sorts of vegetables in raised beds growing all around the neighborhood house. Two girls want to water the corn and squash so I show them how to hold the hose to water the soil, not the leaves. "We don't need help," they tell me and water the leaves. I'm on a winning streak.


 After two minutes they get board, so I finish up the watering. On a hot day like this I can't help "accidently" spraying a few kids. The boys who were playing the game on the pavement dare me to soak them and I do. This is summer camp after all, and we all need watering. The councellors  round up the kids and sing my favorite song I love to hate: "I'm scooping up a baby bumble bee. Won't my momma bee so pleased with me?" It starts with scooping and ends with puking. It's not a pretty song and it advocates cruelty to bees. Just great.

Before we head off on our walk, I take the group of 12 youngsters to a garden bed. I take a male blossom off the plant and close the top. "Do you know how to act around bees?" I ask. Don't do this, one girl demonstrates and she runs around flapping her hands and screeches." "Yes, that's exactly what you don't do," I say. You need to take a deep breath and move very slowly, like in Tai Chi. I take a male blossom off a squash plant. "Do you know what's in here?" I ask. "Is it a bee?" "Yes, and I'm going to see if she'll crawl on my hand." I can see a frisson of revulsion shiver through a girl's shoulders. "I'm scared", she says. "It's going to be okay," I say. I open the top of the blossom and she flies up and back into the squash plant. "You see, she doesn't want to bother me," I say. She just wants to pollinate this squash. And I explain how bees take pollen from the male blossom and put in on a female blossom so it can produce a squash like the ones we see developing on the plant. "Without pollination those squash would have died," I explain.


 I am relieved to be working with the youngest of the kids. They are wee 6-8 year-olds dwarfed by their huge backpacks. We head to the school garden. "It's a bee nest!" They shout and point at a tree. Perched above the cars on a boulvard tree, a classic paper wasp nest hangs from a tree. Aha! This is a teachable moment. I explain that the wasps chew up wood from the fences and create a paper pup which they form into a nest. Winnie the Pooh is all wrong, I say. The illustrator didn't know anything about the difference between wasps and bees. If this was made of wax it would melt and fall off the tree. "Oh, now I see," one bright little girl says, the light dawning in her eyes. Success!

"What would happen if you threw a soccer ball at that nest?" a boy asks. There's one in every crowd. "You would get stung because the wasps would try to defend their babies," I say. But if you don't bother them, they won't bother you. Then I explain to them my ritual of giving a sacrificial piece of salmon to a hungry wasp at a picnic. I tell them to take their picnic plates inside as soon as they finish eating and keep all garbage under a tight lid. Then I tell them to pour any sweet drinks from a can   into a glass or a bottle with a lid because wasps can crawl into cans and you can get stung by accident when you drink from a can. That's wasp safety 101. "What if you kick a wasp and step on it?" the same boy asks, and the questions continue.


When we get to the garden, I see it's going to be tricky to get everyone in a spot where they can feel comfortable. We are pretty squished for space and there are bees everywhere. "Please stay further away from the flowers if you are afraid," I say, giving them a way to feel safe in the garden.

"I'm not really interested in this garden, one girl says, full of summer ennui. "This is my school garden."

"Well, maybe we can see something new," I say.

I give them my spiel, talking about bees using the examples of what we see in the lavender, wooly lamb's ear, perovskia, rudbeckia and echinacea. I explain that the blonde bumble bees are the males and they don't sting. "You can even catch them in your hands. Do you think I should do it?" They dare me and I catch a little blondie and show how he flies away from inside my hands back onto the flowers. "Do it again! Do it again!"


 Then I see a wasp chomping down on a bee caught in a spider's web. When the wasp leaves I take out the dead honeybee and show them. It takes a while to convince them she's really dead, but then they take turns touching her and I leave her on the fence for them to observe. "Can you break that spider web so it doesn't catch any more bees?" the girl says. This is the girl that was repelled by bees about an hour ago.

We form a circle and do the bee dance before the kids settle down for their snack. One boy tells me a tall tale: "My friend got scratched by a bee and my brother punched the queen and stepped on it!" he claims. "That's an interesting piece of fiction," I say and move on.


We walk back to the neighborhood house past the wasp nest, having had a good safari in the heat of the midday sun. I walk down to the Cedar Cottage Community garden where beekeeper Peter has opened up the hives and is looking for a queen. "I hope he doesn't punch her and step on her," I think to myself and head down the hill for a long, tall glass of iced tea.

Cypress Community Garden Pollinators


Madame Beespeaker had a marvelous day off today doing some of her favorite things: eating lunch at Aphrodite's Organic Delights, touring gardens and thrift shopping. Yes! These lovely bees are enjoying the vanilla scented Joe Pye Weed in the Cypress Community Garden. Note the odd morphology of these blossoms. I am not seeing much pollen here. I like capturing more than one bee on a plant. Bees seem to like to have space around them when they forage, much like me at the supermarket checkout. If someone gets in my personal bubble, I need to take a deep breath and  try to shift to  get away from the tailgater. The other day it was hot, I had a migraine and I snapped: "Could you please give me some space?"  I mean the woman was acting like I wasn't there and it was really bugging me.


I see bees bump one another out of their personal bubble, even bees of their own ilk. The larger bees often win, but not always. Sometimes the plant is so delectable that they tolerate the nearness of other bees. Kind of like me, when I'm tucking in to Aphrodite's delectable vegan cheesecake. I am very focused. Everything else in my range of vision melts away as I immerse myself in the cheesecake and nothing but the cheesecake and my iced chai. Does Joe Pye weed taste like vanilla cheesecake to a bee?


It was overcast today and I saw a few yellow leaves fall here and there. At first I would think it was a butterfly, but my heart sank as I saw it was a yellow leaf or two fluttering to the shadows on the ground.  I have had migraines the last two days with the humidity and heat, so today was a welcome relief. I can see into the future on days like this, and I spent the day imagining dresses inspired by bee and hummingbird plants. I was quickly brought to earth by the Chinese Canadian lady who owns the second hand store where I was perusing dresses. "That will never fit you," she said bluntly, "Maybe a friend, but not you, lady." Thump. Sound of a dreamer's dreams hitting the floor.


Can't you imagine a gown inspired by brown-eyed Susans and sneezeweed?


These gardens along the railway tracks are fascinating. Bordered by a hedgerow of blackberry they form pollinator corridors in our city. Linked up with gardens on bike lanes, they would form a strong network of passages for birds and insects. Wouldn't it be wonderful to turn all the disused rail lines into pollinator corridors across Canada? Told you I was in a dreamin' mood.





By the time I saw this skipper sipping nectar from a cosmos I was ready to head to Beaucoup Bakery for an iced tea. There should be tea rooms at regular intervals along the national pollinator pathways. Make mine jasmine green tea with a hint of rose and a fat brioche stuffed with hazelnut cream.


As I saw a honeybee attempt to sip nectar from one of these hardy fuschias it occurred to me that this plant is almost like a bee plant wearing a humming bird plant--purple underskirt for the bee, and red cape for the hummers, but those long stamens are definitely bird-sized. I wonder if these get robbed for nectar or if the double structure prevents that from happening. Watch your fuschias and tell me what you see!

A Strange Little Critter: New Wasp on the Block


 My, what big eyes you have! This little creature was pollinating the Angelica Sylvestris. It has something strange going on on its thorax. This is one time I wish I had netted it so I could check it closer. It has a damaged wing, so it looks like it has been through the wars.


 This blurry photo shows the pattern on its back. It's tiny--about a cm long.

ETA: Phil from the blog Cabinet of Curiosities has helped me identify this as a digger wasp, maybe the square-headed digger wasp like this one taken by Terry Thormin: http://www.pbase.com/terrythormin/image/128851647


 I love the way this wasp was balancing its back legs on a sunflower leaf to feed on the fennel nectar.


Here's another small wasp with a distinct pattern, a kind of window pane on its thorax.






 This is dangerous-looking milk thistle.


 I am really enjoying the shades of the hummingbird sage I planted from seed. It blooms in shell pink, white and scarlet.


A honey bee landed on my glasses and then crawled onto my hand and tried to stick its tongue in between my fingers. I think this is because I had a gig as the Queen Bee in the morning. I use a witch hazel with lavender to remove my makeup and the bee must have been attracted to the scent of the lavender. This has happened to me before when I rub lavender blossoms with my fingers. So you need to be aware that your cosmetics may attract bees!
