Some odds and ends from the USGS Bee
Inventory and Monitoring Lab.....
Paul Williams writes:
Yes, B. sandersoni is very variable in colour pattern
and T5 may be black or yellow in both sexes. But T5 can also be white
(confirmed from barcode analysis), at least in the south of its range.
And John Ascher mentioned that B.
sandersoni often has very limited amounts of black in the center of
Matthias Buck pointed out that we had
forgotten to include the 4 eastern species of Podalonia (Ammophila
look-a-likes) in the Sphecidae guide....those have now been added along
with the associated literature by Erika Tucker
Harold Ikerd mentioned that when gluing
bees instead of holding a glue bottle he runs a short line of glue on his
hand and dips the side of the pin in there. Very handy as our hand
usually follows us around and we are unlikely to forget where we put it.
I have used the now the past couple of days along with the magnetic
wrist pin holder and it has increased my bees per hour. I have also
gone back to using the glue gels...they have much longer open work times
than white glues and they dry crystal clear.
Coelioxys and Megachile
A series of line drawings from Baker
and Mitchell of Coelioxys and Megachile have now been added
to the species pages for those groups.
I discovered last week that Canadian
provinces were only incompletely scored for many presence of Megachile
species. I have updated those. Recall that a list for a
province or state generated from the guide does not mean that the species
has been detected there, it just means that there is a possibility that
it COULD be detected.
Female Andrena Guide
The following character was added to
the female guide to help resolve A. persimulata and A. platyparia....an
easy character, for once.
A. persimulata - Easily identified
by the presence of a large projecting knob or large swelling at the bottom
of the lateral face of the mesepisturnum about half way between the front
and mid legs A. platyparia - Not as above
What 2 Halictidae species from the same
genus are illustrated in the map below? Yellow equals all USGS database
records, Blue is mystery species 1, Red is mystery species 2. Answers
at the bottom.

From Field Work
Not the mud slick,
not the black weedy water
full of alder cones and pock-marked leaves.
Not the cow parsley in winter
with its old whitened shins and wrists, its sibilance, its shaking.
Not even the tart green shade of summer
thick with butterflies
and fungus plump as a leather saddle.
No. But in a still corner,
braced to its pebble-dashed wall,
heavy, earth-drawn, all mouth and eye,
the sunflower, dreaming umber.
Bees are not optional.
Answers: Augochlorella aurata is
species number 1 and Augochlorella persimilis is species 2...we
have not collected A. persimilis outside of the mountain and piedmont
