Dear All,            May 9, 2007
    On May 7, in my Cambridge Pine woods, I noticed a small leafy 
Liverwort that was loaded with sporangia; near the base of a White 
Spruce on the north side. Keying to Genus may be difficult (assuming I 
make time to do it) because the gametophytes are in terrible shape.

    On May 7, in these same woods, I saw numerous white butterflies of 
size and flight that suggested Mustard White. I was out today again and 
a definite Mustard White posed a few feet away, with wings raised, and I 
could clearly see the greenish veins. I was there from 9:00 a.m. to 2:45 
p.m. and about 1/3 of the time there was one or more in view. There are 
no Cruciferae in these woods but the introduced Cardamine used to be 
abundant in the nearby Cornwallis meadow (~100 paces away).

    Beetles were flying on May 7; in addition to the usual Ellychnia 
(fireless Fire-fly; first ones that I recall having seen this year) 
there was an Elater, a Hydrophilid and a Cerambycid that has me stumped 
(23 mm long, narrow, parallel-sided & light brown) so I am wondering if 
it may be of some look-alike Family.

    The large parchment-like cocoon that I saw on Apr 20 has gone 
without a trace.

    Also on May 7, I cut a fair sized very crooked White Pine and sawed 
one slab off a 60" length as a prelude to sawing out a few planks. So 
with a good smell of fresh pine, the tree today was fairly swarming with 
Bark Beetles (Scolytids of three or more species) and a few Clerids (of 
likely only one species).

    The season of everything happening at once is upon us. And Black 
Flies are just starting to appear but not yet biting.

Yours truly, Dave Webster, Kentville
