Close to 28,000 items have been viewed since Dec of 2010. I am certainly enjoying the increased interest in my blog. It is a lot of fun to write. I love getting stories from other countries. This makes it all the more interesting.
Keep the stories and photos coming. Other mason bee enthusiasts are very interested in how it is done in other parts of the country.
Thank you for joining. It provides me with feedback on how I am doing with this blog.
I phoned you a few weeks ago to ask about where to place our new bee house. You suggested a location that faces east and gets morning sun, and then added that putting a shelter around the house to keep off rain and wind would be a good idea. Finally, you asked that if I built such a shelter, I should send you some photos.
The photos are attached. The shelter faces east in a place where it should get morning sun, and it’s stained a dark brown to absorb heat. It’s about 60 meters away from the apple tree we are hoping the bees will pollinate. I hope that’s not too far. The bees may find flowers and other plants closer by and never make it to the apple tree. But we’ll keep our fingers crossed.

This is where the shlelter is located. East facing,
with trees as added wind protection.

Quicklock corn nesting trays. Above the Royal, there
are two sturdy Emergence Shelters
with cocoons- waiting for warmer weather.

Joe phone me today to let me know he has some interesting ‘stuff’ in his nesting trays. More later…..
I read in a blog the other day that washing cocoons is not necessary.
There are two good reasons for washing mason bee cocoons.
The first reason is to remove the majority if not most of the adhering mites. The washing process includes a soak in cold water to remove mud and feces. Then, cocoons are gently sprayed with cold water (while in a colander) to remove any excess mites. If excessive mites are present (even after washing) mites are removed by rolling the dry cocoons gently over a metal window screen (not plastic- it is not abrasive enough to remove mites).
The second is to remove debris and mud and feces from the cocoons so that cocoons can be candled for parasitic wasps. Candling Mason bees was first introduced and developed by Joe Sadowski from Burnaby British Columbia Canada. In a dark room, and over a bright light, parasitized cocoons can be identified, removed and destroyed. By removing these wasp parasitized cocoons, there is less of a chance for the wasp population to increase and potentially wipe out your bee population.
It is pretty neat to see what bees and other insects have been up to during the previous spring by candling cocoons and having a ‘closer look.
I recommend caring for your mason bees by harvesting and cleaning your mason bee cocoons in the fall.

It is right in the middle of the mason bee season now. Stores have stocked up with product and individual customers buy from us direct. When it is so busy, I do collect stories with pictures on a daily basis for this blog. I have some catching up to do! Here is one of these stories from Larry.
We are cleaning our bee condo, and it appears as if we had a few of the
cocoons that had opened and there is larvae in them. Are they dead? Also, they seem to be larger that the the cocoons that are still intact (and which we have cleaned to remove mites, etc.)
My first response was to ask for a photo.
“Yes- please send a picture. It sounds like you have some beneficial wasps.”
Then I received this picture, it confirmed that this is a beneficial wasps. What is neat about these insects is that different species collect different live food items for their young. They either collect and feed their young with spiders, moth grubs or aphids. If one of the wasp eggs did not develop, there might be evidence of the kind of wasp is growing in the nesting tunnel.
This grub or pupae still has a lot of developing to go through before it is an adult. Further development starts when spring temperatures are on the rise.
These grubs are very fragile. I usually leave them in their nesting tunnel, remove mason bee cocoons in the remaining nesting tunnels, close the nest up and set it outside again.
