I just spent the past 2 1/2 hours harvesting about 2/3 of the cocoons from the nesting tubes, washing away the dirt and letting the cocoons sit in a bath of (weak) bleach water. I’m happy to report that I saw no parasites this year and no evidence of mites (it there had been mites, I would have seen orange or red spots on the paper towel where the cocoons are drying). Once the cocoons are dry, I will be putting them in the special humidifier box I bought from Crown Bees and storing them in the refrigerator until spring. I will finish harvesting the rest of the cocoons later this week.
Another gorgeous day…and another morning of watching my bees at work. Once again, I laid on the porch just to watch my lovely ladies. Besides being fascinating to watch, there’s something peaceful and soothing about laying there as the buzz of their wings surround me on their way to the nesting tubes. Where once they stopped to check me out, they now ignore me and go about their business…I think they are quite used to me being a voyeur.
I noticed that just since yesterday, almost all the tubes in the bottom portion of the one house is filled. I’m also glad I put more tubes in the house roof and filled a coffee can with more…the girls are already making use of them. I have a feeling that I may need to get more tubes, knowing the bees still have about a month to go with their nesting ritual, before they die. I have another house coming in the mail…I just need to get more tubes.
I have a light work schedule today, so I went out the front porch and laid down to watch my mason bee gals at work. I could have stayed there all day, they’re so fascinating to watch! They pretty much ignored me and kept working. Some would fly into a tube, put down bee bread, then emerge from the tube, only to back in to lay an egg. I captured much of the action on these videos.
Several of the new bees were content to rest on my hand after they first emerged from their cocoons. One thing I learned….after spending all those months eating bee bread (pollen), it has to go somewhere. So, I had bee poop all over my hand!
Yes, I feel like a proud mom! All but about 40 of my harvested cocoons hatched! Watching them first mate, then start laying eggs in the tubes has been so rewarding.
But let me back up a smidge…last fall, my Asian pear trees had produced more fruit than the previous year. Not only that, but the one variety that was typically bland tasting was the sweetest of the three trees! I really believe my bees contributed to a good fruit yield.
I added a nesting block from Crown Bees this year…and the girls have been so busy, I had to just order more tubes and reeds to accommodate them! I just have to find something to put them in (I think my husband needs to make a box for me this weekend).
I also got my neighbor to join in on the fun. She just bought a bee house and tubes, so I gave her a bee attractant cloth…maybe some of my gals will migrate over to her bee home. Crown Bees still has cocoons that need homes, so I ordered more of those, too. I plan to give some to my neighbor to really get her started. The fruit trees have pretty much dropped their blooms, but there are still plenty of flowers (lilac, roses, and others) around for them to continue making bee bread for their brood.
By the looks of things, I think I’ll have twice as many cocoons at last year. I plan to give the extras to Crown Bee (in exchange for nesting materials, maybe).
In preparation for after the bees are done laying eggs, I purchased a net sack to keep out parasites, etc. I also purchased a humidifier for the fridge, that will make it easier to store my cocoons.
Around the end of 2011, I contacted a local honeybee keeper and asked him if he wanted to put a hive on my property. He asked me why I wanted them. I told him several reasons:
- I knew that bees were in decline and wanted to help.
- I have three Asian pear trees that were declining and felt help with pollination would give them a boost.
He told me that honeybees wouldn’t be able to help with that because they tend to be active long after fruit tree blooms have fallen off. He asked me if I had heard of mason bees. When I said no, he said I should do some research and that these bees were also called orchard bees since they are beneficial to pollinating vast orchards.
So, off I went to the internet in search of more information.
I found out that compared to honeybees, mason bees had quite a few differences:
- Mason bees didn’t live in hives,
- they didn’t sting (a big bonus since I’m allergic to honeybee stings)
- they didn’t swarm
- they don’t produce honey (a bummer, but their pollination benefits offset this)
- they required much less equipment
- they cost less to maintain
I ordered nesting tubes, liners and natural reeds from Amazon.com since they were a bit cheaper than some of the mason bee supply companies. I also ordered 25 cocoons from Ruhl Bee Supply.
When I got my cocoons, I put them in my fridge until it was time to put them outside. I put the nesting tubes in a long can and hung it from one of the pear trees. Once the trees starting blooming, I put the box in the can and waited for the bees to emerge. Unfortunately, they didn’t like the location and immediately flew off.
Not to be deterred, I ordered 50 more cocoons fro Ruhl, along with a bee house (instead of the can). I also did more research and found that I should place the house/tubes/cocoons in a south or southeast location so morning sun can warm the bees. I also needed to create a mud source (clay based, not sandy) nearby. I have a wrap-around covered porch that would be perfect. Plus, birds never seem to fly under the porch roof, so I thought the bees might be more protected than in the trees. It was a good choice! My bees emerged, mated, and got busy!
Watching the bees was so fascinating!
At the end of September, I removed all the tubes and opened them up. One of the books I had purchased said to look for parasitic wasps and mites. I found two of the wasps, but very few mites. The book also said to rinse the cocoons in a colander (they are waterproof), then put them in a mild bleach solution (1 tsp. bleach to 4 qts. of water), then remove them to a white paper towel to dry. If there were any yellow or orange stains on the paper towels, then mites were still present. I was lucky and had none. All in all, I had over 400 cocoons!
Once the cocoons were dry, I got a plastic container and placed a wet paper towel in the bottom. You need some moisture since modern refrigerators have very little humidity.
This container also had an insert so I could separate the wet towel from the small box that contained the cocoons. Closing the lid, I put it in my refrigerator for the winter.
