Re: [beemonitoring] Insect trap idea - cheap "plexiglass"
- Laura -
Cheap alternatives to plexiglass:
1. The plastic from a laminator machine. Just run the machine without
anything to laminate. The resulting clear plastic is fairly stiff,
however, you will have to attach the panels to wire frames (to make them
stiff enough to stand upright).
2. Another source of cheap clear plastic can be found at garage sales -
all kinds of (generally ugly) framed artwork can be obtained for little
money - take the plexiglass (or whatever plastic is substituted for glass)
and recycle the rest. For a more expensive source, visit thrift stores.
I'm not sure how long the various plastics hold up in the sun, but they
should be fine for at least one season.
Good luck with your study - sounds like fun.

- Thank you for all of the great tips! I'm afraid I will have to revise my plan a little bit, however. The plexiglas sheets turned out to be quite beyond my budget (150$ a sheet!). My modified version will replace the plexiglas with white bridal tulle as netting and PVC pipes at the four corners. I think this will turn out to be much more affordable. Other modifications: (1) the cone can be made out of a flexible vinyl sheet (2) I found a PVC adaptor at Lowe's which will allow me to connect a 3 in diameter PVC (the top of the cone trap) with a 1.5 in PVC (in the bottle of alcohol). If you're curious, I attached my alternate trap plan.
Again, thanks for all the help!

I like your idea. I recall a somewhat similar trap that I read about that was deployed in what I think was Denmark, possibly it was the Netherlands. They used a large yellow pan trap and then used plexiglass baffles similar to yours. They caught quite a few bees in the trap. I think a number of us have seen bees flying down and over pan traps without actually going into them. Additionally, I was talking to some beetle heads this weekend who said they often get good numbers of large bees in their window pane traps (the bees and beetles strike the window and fall into a narrow pan of soapy water or glycol) adding credibility to using something like you will be building. I would say the most problematic part might be the cone part which looks difficult to fabricate.
It would be great to make a set of these traps and run them concurrently but vary whether they have wings and cone parts on or off to test to see how many additional capture they generate. We have been running larger pan traps all this spring and have found that bees easily hold up a week in just plain water. Salt in the water appears to keep the bacteria and algae populations more in check. By the end of summer we should have more information and look forward to seeing how your trap evolves.

Further in Summer than the Birds
Pathetic from the Grass
A minor Nation celebrates
Its unobtrusive Mass.
No Ordinance be seen
So gradual the Grace
A pensive Custom it becomes
Antiquest felt at Noon
When August burning low
Arise this spectral Canticle
Repose to typify
Remit as yet no Grace
No Furrow on the Glow
Yet a Druidic Difference
Enhances Nature now

I hope it is okay to send this out on the list-serve. I am trying to design an insect trap that mixes the Texas cone, the window, and the pan trap. I pieced together ideas from different papers and pictures that I saw to come up with this idea. I am hoping to collect more than just bees, although bees are a critical part of my experiment. The idea is that insects will fly into the plexiglas and either fly up into the cone trap, or fall down into the pan trap.
It had to be somewhat cheap, easy to set up and take down, and able to withstand some weather. I'm a brand new grad student, so I welcome any comments and suggestions that you might have on whether this will actually work!

Does anyone have any suggestions as to where to find a few hundred
cocoons of Megachile rotundata at this time of year? I have a student
who would like to do a pollen bioassay experiment this summer with a
commercially available (or non-commercial, if someone has a research
supply) cavity nester and the only one I can think of that might be
available to forage this summer would be Megachile rotundata. The
suppliers I talked to don't have any left and also don't like dealing
with such a small number of cocoons.
Putting out trap nests here has been remarkably unproductive over the
years, so I can't count on getting an abundance of any species other
than mud daubers.
Any suggestions would be very welcome. I would also like any
suggestions of native Megachile species in the eastern U.S. that
anyone has had particular success getting in trap nests as a
possibility for the future. Megachile rotundata is certainly well
naturalized in this area, but I would like to have a native cavity
nester other than Osmia (unless someone knows how to delay Osmia
emergence successfully for the summer) for research use.
Thanks for any ideas,
