Below is a list which contains the names of 74 species that are known to have occurred East of the Mississippi River in the U.S. and Canada at some point (you will just have to imagine that the Mississippi gets up to Canada) that a group of active collectors have not seen in the past 20 years.
The following individuals contributed to that list:
We are looking for anyone with ANY records for any of these species from ANYWHERE during the past 20 years. Its fine if those records are from Western North America. Note that we are starting with Eastern species simply because we are more familiar with that group and there are fewer species involved (approximately 775). Some of the species and names below come from groups that have taxonomic difficulties so the presence of their name here may simply be the result of lack of recent revisions that can clarify their status. That said, most of these names do represent legitimate species, almost all of which have always been rare (correct me if I am wrong please).
After sending this list around to people like you, we expect that additional recent records will be discovered for some. At the end of the exercise we will tabulate the species, annotate what is known of their habitats, geographic distribution, time or year, etc. and provide instructions as to where to look and collect to see if any of these species can be re-found.
[Side Note: There are approximately 800 breeding species of birds in North America....one would expect that people would be very concerned if a tenth of the species on that list hadn't been seen in the past 20 years...so, why aren't you concerned about these bees?]

Ah to be alive
on a mid-September morn
fording a stream
barefoot, pants rolled up,
holding boots, pack on,
sunshine, ice in the shallows,
Rustle and shimmer of icy creek waters
stones turn underfoot, small and hard as toes
cold nose dripping
creek music, heart music,
smell of sun on gravel.
I pledge allegiance
I pledge allegiance to the soil
of Turtle Island,
and to the beings who thereon dwell
under the sun
With joyful interpenetration for all.

Centris errans can be readily seen in Miami-Dade County visiting Brysonima lucida (Malphighiaceae) in pinelands and gardens when it flowers in the spring. Hong Liu and I did a pollination study of our native rare cowhorn orchid, Cyrtopodium punctatum, using naturally occurring plants at Fairchild Tropical Botanic Garden in Coral Gables and found that Centris errans was the only pollinator of the orchid.

Interestingly, in a related study, we found the invasive Centris nitida was the only documented pollinator of the invasive orchid Cyrtopodium polyphyllum.

I have also caught Centris errans visiting a flowering plant of Byrsonima lucida in my residential garden in Fort Lauderdale, Broward County a few years back.

Res. 1:107-118) but the field work was from 1989 so I guess it doesn't quite make your deadline. Since the bee seemed to be locally common in 1989, its demise by 1990 seems unlikely since neither its floral hosts, nor its nest sites were likely to disappear. I also have a short series of what I've identified as Osmia illinoensis from the Lost Pines region of Texas - the ID is only tentative so I wouldn't scratch it from the list yet.bestJackJohn L. Neff
