RE: [beemonitoring] catching bees on cactus
- We designed our own pollinator vac (attached pic) for use in a number of habitats, including ones that had cacti and mesquite. We are pretty happy with it, but you still have to develop a technique. Since we made ours BioQuip came out with something comparable and reasonably priced. I am not suggesting it is better than other methods but it is one alternative.

Subject: Re: [beemonitoring] catching bees on cactus
Having done lots of cactus collecting, I've found two techniques that
(1) the test-tube method, using a vial with a diameter just slightly
larger than the flower, but you have to be quick, and time it for
when the bee is distracted (that is, it works mostly for females, but
not for males).
(2) the "jedi" method, determining the flight path of bees
approaching or departing, and intercepting them in clear airspace
either before or after they land. This keeps the net away from the
plant, but requires very good reflexes and a lot of patience.
a variant on this technique which is less reliable is the
"misdirection" method, where you hold the net off to one side of the
flower, and use a large object with your free hand to scare the bee
off the flower in the desired direction - hopefully, right into the
net. In principle, it's good, but bees don;t always do what you
expect when you scare them.
The good thing is that there should be only a very few species
visiting, and it won't take many specimens to complete the list.
