Dear All,            July 28, 2007
    We headed to Huntington Point this afternoon for a break from heat 
and a beach walk to refresh sight recognition of the Long Legged Fly 
(_Liancalus genualis_ Loew)  followed by corn; two out of three.

    None of the seepy areas had either the Machilidae (Bristletail ?) or 
the _Liancalus genualis_. Previously I had seen them Aug 15 & 18, 2002. 
Is this perhaps too early or did they have a hard winter ?

    There was more recent fallen rock than I have ever seen on a fundy 
beach, most or all from beyond reach of spray so presumably due to an 
abnormal number of freeze/thaw cycles.  Whether most of it fell this 
spring, as opposed to previous springs, I can't be sure, but it looked 
unweathered.

    A highlight of sorts was one Mustard White working flowers in a 
small patch of. Sea-Rocket (_Cakile edentula_), the first I have seen on 
the shore or away from Kentville. I was able to watch it for several 
minutes, from just a few feet away, and I saw no indication of egg laying.

    When we walked west at about 2:00 p.m. there were large numbers of 
Bumble Bees (~25/m^2), all of one species, working patches of 
Sea-Lungwort (_Mertensia maritima_) for nectar and when we came back at 
about 4:30 p.m. they were still there, busy as usual.

    The Beach Pea (_Lathyrus japonicus_ var) is now abundant along the 
cottage section west of the road end and was loaded with pods ready to 
cook. Orach (_Atriplex patula_), a very good green, is also doing well 
there now.

    At about the time the corn water was hot enough (Coleman Stove; 
bought 1956 !) to give off the odor of cooking corn, we started seeing 
Rove Beetles (_Philonthus  furvus_ Nordmann probably) flying to and 
around the stove and this continued off and on while the corn cooked. 
They fly rapidly but like a balloon that is releasing air; very erratic. 
Once we started eating corn, they turned attention our way, and landed 
on nearby rocks or on boots/socks when least expected. Usually only one 
at a time came in and they seemed uncertain what to do next, even after 
I put some cobs, stripped of kernels, on a rock.

    When packing up to leave I, by accident, transferred a speck of 
cooked kernel to the handle of a fabric tote bag and the next thing I 
knew, a Rove Beetle, had found it and was vigorously attempting to chew 
the kernel.

Yt, Dave Webster, Kentville
