White Admirals and Sparrowhawks
in the Wood
June and July are the key times to
find White Admirals in Old Park Wood and it is a good site for this uncommon
butterfly. It is a woodland specialist, liking sunny glades and rides with
bramble flowers to feed on and honeysuckle to lay its eggs. It is a “late
emerger” reaching the butterfly stage comparatively late in the
summer, the pupa having overwintered wrapped up in a honeysuckle leaf. The
butterflies are essentially black and white and have a strong flight with
wings flicked stiffly. In previous years they have been common along
the main track around the entrance to Limberlost wood and the main track is
a good place to look, wherever there are brambles in flower. Like many
species the White admiral benefits from a woodland management that creates
sunny areas for basking and flowers to open – cutting back bracken,
coppicing along rides and glade widening.

For me, one of the most noticeable
effects of re-establishing coppicing in areas of Crow Wood has been an
increase in the number and variety of insect species of all kinds. …and this
has an impact on bird and reptile populations. Although migration this year
has been very poor, I am still very hopeful that the Spotted Flycatchers
that nested last year will return this year and if they do it’s a fair bet
they will take a few butterflies. C’est la vie. But I will be a little cross
if the Sparrowhawks have them for breakfast, delighted as I am to have them
nesting again in a tall Scots Pine, nowadays a flycatcher is a much rarer
animal altogether and a species that is really struggling.

| A Crab Spider on the bloom of a Devils Scabious, Crow Wood.
Usually white, they are very small and can be found on
flowers in summer waiting for flies to drop by. This one was sitting on
Devils Bit Scabious, a plant of damp, open rides and great for insects, that
flowers in July.

| Oak Bush Cricket, Crow Wood. A
common cricket of late summer that spends most of its life in Oak trees just
munching leaves.
|
 |
| |
|
| A Spotted Flycatcher, Crow Wood. A summer migrant that
like the cuckoo is getting rare in this country now. This bird was one of a
pair that tried to nest in 2008 but failed. I have not seen any in Old Park
Wood this year, which is very worrying. It is a government Biodiverisity
Action Plan (BAP) species and populations are being monitored. |

|
| Tatty Silver Washed Fritillary, Crow Wood.
A fast flying woodland specialist, that needs wood
violets to lay its eggs and so benefits when woodland is coppiced. On the
wing in July and August but not common, and difficult to spot as it rarely
rests for long.

| A Tiger Beetle, Crow Wood. Likes
sitting in the sun, mimics the colours of a wasp to deter predators but is
harmless.

| |
|
| A White Admiral, Crow Wood.
A late summer butterfly that needs honeysuckle to feed
from and lay eggs on. It likes sunny rides so the best place is the main
track north of Limberlost although it occurs in small numbers all over the
wood.
It benefits from the coppicing and
ride clearance that encourages its food plant to grow.

A Glow Worm, Crow Wood
Glow-worm - seen around the wood in
clearings anywhere in Old Park Wood – still, dark nights in Late June are
the best time to look. It’s the female that glows to call in males. This one
was on a coppiced stump on mid-summer night.
