Brown Hairstreak fFeld Trip to Bernwood 22nd August 2004 |
|
Sunday 22nd Bernwood Forest. Ten UTB
members and two guests from Beds & Northants Branch turned up for what
was to prove the most successful UTB Brown Hairstreak Field Meeting ever
(and I have been on all seven previous ones). We were unsuccessful all
the way down to the Meadows. In the most northerly of the Meadows we
were able to add two more eggs to those found the previous Friday but
still no adult. We then crossed to the known Assembly Point on the
southern boundary of the south Meadow. We had immediate success with two
seen flying in the central oak tree, one of which was identified as a
female when it settled briefly. In the meantime I had been examining a
suspect "dead leaf" with my binoculars, when the scope (provided by our
guests from Beds & Northants) was focussed in it proved to be yet
another Brown Hairstreak. Obligingly it then opened its wings to allow
us to identify it as a female. We decided to eat lunch keeping an eye on
this settled female hoping it might come down to the nearby blackthorn.
However, it flew unnoticed but we decided to search the blackthorn just
in case. Una Fenton's keen eyes almost immediately picked up a settled
female and whilst the rest of us examined it our guests found another a
bit farther along. Both only remained settled for a short while before
flying up into the trees. Just before they did this another female did a
fly past. We then crossed back to the opening back into the first meadow
where a "Gatekeeper" flew across our path - or was it? Fortunately, it
settled on the blackthorn when it turned into another Brown Hairstreak.
It then flew down to a blackthorn twig a foot from the ground where it
was identifiable as another female and then to our joy it proceeded to
lay an egg. The egg was closely examined when she flew on and settled
again to give the photographers a good opportunity. Making our way up
the field edge to Hell Coppice Richard Soulsby had another brief glimpse
of a female disappearing over the blackthorn. Half the party departed
before we made our way to the M40 Compensation Area where we had no joy
probably due to the deterioration in the weather conditions whilst we
were there. However, two of the early leavers had more success
seeing another female egg-laying just before they got back to the car
park. Those who made it all the way to the Compensation Area
were rewarded along the main ride by pristine Painted Ladies (running
into double figures) and a gorgeous Clouded Yellow. Total Brown
Hairstreak Count 11 adults (although I suspect at least one of the first
low level females seen was previously seen in the nearby oak tree) and 6
eggs (two freshly laid). Total species count 15 - Small Skipper, Clouded
Yellow, Brimstone, Large White, Small White, Green-veined White, Brown
Hairstreak, Small Copper, Common Blue, Holly Blue, Red Admiral, Painted
Lady, Speckled Wood, Gatekeeper & Meadow Brown. A truly successful and
memorable day!
