All,

This is a tad late, but still relevant, the idea, as with the other months.=
.... is to spotlight groups of plants that are the brood food source for rar=
e or understudied bees. Sometimes these bees are truly rare, somethings t=
hese bees are just overlooked, and sometimes we have it wrong and the bees =
we associate with a set of plants are not so narrow, but simply so understu=
died and uncommon that mistakes are made.

Thanks to Jarrod Fowler for various reminders and for compiling the followi=
ng site with information on eastern specialist bees:

Pollen Specialist Bees of the Eastern United States<https://jarrodfowler.co=
m/specialist_bees.html>
Pollen Specialist Bees Approximately 25% of the ~770 species of bees native=
to the Eastern United States are pollen specialists. Pollen specialist bee=
s evolved a continuum of facultative or obligate associations with flowerin=
g host plants (Cane & Sipes 2006; Hurd et al. 1980; Linsley & MacSwain 1956=
; Robertson 1925).

So here goes. June.

Chelostoma philadelphi - In places they have been out since May, but still =
to be found in June. Mostly found on planted (non-native) Philadelphus (mo=
ck orange plants in yards,....) but, friends, what is going on when you fin=
d them in locations where there are not Philadelphus plants? The native P=
hiladelphus plants are around, but rare. Do we even know if the native Phi=
ladelphus plants attract this species?

Loosestrife (Lysimachia not Purple Loosestrife (Lithrum)). So, this is an =
oil producing plant group that attracts the oil using bees Macropis and the=
associated bee nest parasite Epeoloides. All are now considered uncommon =
to rare, but formally, not so rare. All are considered to require Lysimac=
hia in their pollen load, but this is perhaps an open question for the supe=
r uncommon M. steironematis. It has also been assumed that they are only o=
n native Lysimachia, recent papers record them on Garden Loosestrife at lea=
st, so keep an open mind. However, catching a bee on a plant is different =
from whether that plant provides a sustainable or required component of a d=
iet. [e.g., You can find people foraging in 7-11, but they probably need t=
o forage elsewhere for a sustainable diet] Today I saw my first M. ciliata =
out on our residual patch of Whirled Loosestrife at the bee lab.

Chestnuts and Chinquapins. The time is now. Time to look for Andrena rehn=
i on these plants bloom to see if that very rarely found bee isn't just a C=
hestnut specialist.

Pseudopanurgus pauper. Listed as a Ceanothus specialist...but is it really=
? Ceanothus is a marvelous plant for bees, so, if you have any in your are=
a you should be collecting off them now in any case.

Cemolobus ipomoeae. In the South Ipomoea pandurata should be be blooming n=
ow and this is an acknowledge pollen source for this early morning bee. A=
nd note...this is a rarely collected bee, all the ones I have seen have bee=
n collected in pan or vane traps, so its not completely clear if they may n=
ot also be found on some of the other native (and perhaps the non-native on=
es too) Ipomoea. Morning Glories are called Morning Glories for a reason..=
..I have collected Peponapis at gray down off of I. pandurata...so, really, =
there could be all sorts of interesting things going on out there while you=
sleep in for the rest of the bees, so get up early on some super warm day =
and check it out.

Colletes francesae - Right now, this species has only been found in the Lak=
e Wales Ridge area of South Central Florida on Sideroxylon tenax in deep sa=
nd areas. However, S. tenax is found to the north of there and, in fact, r=
uns up the coast to the Carolinas. Additionally, there are several more sp=
ecies of this thorny (maybe why its not collected on often) plant. While o=
utside of my bioregion....there are hints here that this plant group might =
make a great plant to promote for pollination.

Look back at May's recommendations as many are still very relevant for June=
..

A Natural History of Getting Through the Year

-From William Alphonso Murrill, The Natural History of Staunton, Virginia, =
1919

NOVEMBER 1, 1895
The mountains are on fire
And everything is dry; insects gone.
My private work this year will be:
Biology, Bible, Art, Geology, Body,
Literature. This term will be devoted
To Art, Zoology, Bibles, Epics, Dramas,
Etc. I find the Entomostraca interesting.

JANUARY 24, 1896
I spent most of the day
Mounting butterflies from India.
This finishes all the flies for this year
Until more are caught.
Poisoned plants at night.
Very warm. The brightest,
Warmest January I remember.

PLAN OF NATURE STUDY FOR APRIL
Birds and flowers will keep one busy.
Make collections of both, and observe
The battles and songs of birds. Watch
For the eggs of Phoebe about the middle
Of the month. Study the circulation
Of the blood in a frog=92s foot.
Take up mental hygiene;
Because it is much needed now.

- Annie Dillard
