    Default Orchard Mason Bees from central NC

    New here today. Just joined up since this is one of the more active sites that pertains to Orchard Mason bees, Bumble bees and other solitary pollinators.

    I have been hanging nests for about 3 - 4 years now and have been getting good block fills and very little in the way of parasites.

    I would like to expand into Leaf cutter and Bumble Bee Nests. The Orchard Bees do a great job on my spring garden and blueberry bushes, so I'm looking to round out my pollinator stocks. Although, I got lucky last year and a BeeKeeper landed 3 hives next door to me. Will have to see if his hives will make it around here.

    Here is a link to my Photobucket album of the nesting blocks and hatching chambers that I use.

    I have a few questions, but I will start them in another thread.

    Hello Gyozu
    What sort of numbers did yo have in the last four years? Did you start by putting out 'traps' or with purchased cocoons? ... and what species do you have?
    Cheers,
    Paul.

    They are all locals as far as i know. I have not purchased any.
    I started by putting out one block with 24 holes and lined with handrolled parchment paper tubes. I believe I got about 10 filled tubes. Next year all 24 were filled. I went to two blocks for the 3rd year and I filled about 40-45 tubes that year. For 2011 I hung blocks with a total of 167 tubes and got about 160 filled with a couple of partials. I average about 9 cocoons per tube. I think the unfilled were due to the paper tubes krinkling and were not suitable for the bees.
    They seem to be the run of the mill "Blue" orchard variety, but I have not trapped any to confirm.

    A picture is worth 1000 words - and your pics are gorgeous!

    I bought an untreated 4x4 but haven't hung a block yet. I had blue mason bees in my wildflowers last year, so they are nesting around here somewhere. My elm tree is suspicious, the east side has woodpecker holes about the right diameter, about 8 foot up. Where did you order the parchment tubes? Or can they just be ordinary paper?
    Stuck in Texas. Learning Permaculture in drought, guess I will teach permaculture in drought. The bees are still alive.

    Glad to hear you chose the 'let them come' philosophy. I have been at it about 6 years and its only recently - possibly due to the safety in numbers - that I am starting to suspect that a third unidentified species is using my tunnels (I am also using Japanese knotweed, teasel and umbellifer stems that I find) as well as a cuckoo bee species. I have Osmia cornuta (c.85%) and O. rufa for most of the rest.
    So are you opening and cleaning all the tubes, or just mostly counting the sealed tunnels?

    I open all the tubes and inspect the cocoons for damage and parasites. I have been leaving any cocoons that are different, but move them to a separate hatching chamber. I brush out all the block holes with a small test tube brush and reload with a fresh parchment paper tube. I wait a week or so before attaching the back. Last year I put a wrap of black electrical tape around the back cover seam to stop parasite entry. I will see how this works. This year I want to try scorching the front of the blocks and wire brushing them. This would be for better gripping surface a better visual look for bees. Also though about some sort of pattern marking for bees to locate their tubes. I see a lot of crawling in an out and checking of holes. Could they be searching for their tube?


    My main concern right now is the warmish weather we have been having lately. High 50's and flirting with 60 during the day. Bee blocks are in the shade on north side of building. Not sure if I should pull tubes and move them to a mini/dorm size fridge.

    When I have seen a lot of apparently obsessive crawling in and out and turning around in paper-lined tunnels, it has often been because the paper has curled inwards just inside the entrance and the bee moves on kind of 'irritated'. If they decide that it's not too much bother then they may cut the paper with their mandibles I caught a moment on camera that shows how much time trimming paper-liner curls can take up

    I take your point that giving them visual cues to where their tunnel is can help - I have put non-toxic food coloring on some of the wooden structures I am using this year... and I am also moving towards the tray system now that I have over a thousand bees. It has started to take a very long time to prepare and inspect and refill paper-liners on nine blocks.

    In respect of judging temperatures, the key thing is that the bees don't burn up their fat reserves coming out early. Fridges are an option but Dave @crownbees warned me to watch out for the dehydrating aspect of modern fridges - the bees still need a certain level of humidity.
