>>>John, you didn’t direct this to me but I’m going to respond anyway.
Certain bee species and a very few bee faunas are well known and can be
repeatedly sampled, so that adequate information can be obtained using
observation or inefficient, highly selective collecting methods. In these
limited circumstances large-scale collecting ("killing") may be
>>>And that’s all that is being said here, at least by me. It depends on what your objectives are and how scientifically worthy they are and if there are alternative ways to gather the data. If the objective is simply to use some pins and fill a bunch of drawers, then your objectives are, in my opinion, unworthy (I could go further but won’t).
However, most bee species are poorly known and most bee faunas are
inadequately characterized if not entirely unknown. The only efficient way
to remedy this is to collect bees on a large scale using highly effective
methods. Alternatively, we can remain ignorant or waste carbon on repeat
visits (spewing pollutants and smashing bees against our windshield en
route) that may not have been required had more effective techniques been
>>>So you mean to suggest that manic collectors, those who buy t-shirts that say “I collect, therefore I am”, don’t repeat their collecting expeditions, or “spew pollutants” or “waste carbon” (angels are they?). I suppose they do their collecting while hovering or from skateboards. Again, I don’t know anyone, least of all me, who reasonably objects to collecting for the purposes you outline (lord knows I’ve done much of it myself) but that is hardly what we’re talking about. Don’t erect straw men. We’re talking about collecting simply for the sake of collecting, or collecting that cannot justify its purported purpose, or collecting that puts bee populations in local areas at risk for no good purpose.
Those who oppose "unnecessary killing" on principal have done immense harm
to bee populations by preventing control of the deer that eat their host
plants. They have a lot more hemolymph on their hands then do insect
>>>I too have remarked upon the high correlation between opponents of bee killing and opponents of deer control. Tell me again: who did that work?

I'm sure it was amusing but had little scientific value.
>>>I doubt the purpose was for the immediate advancement of science or for amusement; it was for a class.
Jim, I'm afraid that many people cannot distinguish Peponapis from the
smaller Xenoglossa (see Bugguide), and until they learn to do so they will
need to document their identifications with vouchers (photo or specimen).
Consubgeneric Xenoglossa can be quite tricky to separate (as are Peponapis
where multiple species occur), so if these are to be separated even more
problematic to rely on observation or sparse vouchers. Thus, squash bee
identification remains a challenge even though these are among the better
I’ll let Jim respond if he wishes.
