We were just finishing our lunch in the grassy
Wicken Fen car park and picnic area (National Trust) on Saturday when David noticed that this grasshopper was also eating its midday meal.
It was an indifferent day weatherwise, with rare bursts of sunshine in between grey cloud. I was surprised to see so many tiny
Common Lizards - some smaller than my little finger - on the edge of the boardwalk. There must have been about thirty, but we weren't actually counting. I expect some had just
been born.
The photos that appear below were taken with a zoom lens. Common Lizards are
protected here in the UK under the Wildlife and Countryside Act 1981. It is illegal to kill, injure or sell them.
I only noticed these head markings (below) for the first time when I uploaded my photographs.
It looks as though the lizard below had lost the end part of its tail ...
This next lizard (below) had a long tail, but there was a particularly scaly patch or fracture plane towards the end where perhaps the tail had re-grown. I don't know whether this applies to all species of lizard, but when a lizard sheds part of its tail in a bid to escape a predator, the lost section moves about for a while, distracting the hunter, thereby giving the lizard time to escape. The ability to a shed (and re-grow) the tail is called '
autonomy'. Re-grown sections of tail have cartilage rather than bone and cannot be shed in the same way. The mere threat of predation can cause sufficient alarm in the creature to trigger tail loss.
The lizard in the photo below clung to the edge of the boardwalk ... Once again, the photo was taken with my zoom lens.
Ticks on lizards are rarely seen with the naked eye, but they
often show up in photographs. Unlike the lizards I have occasionally spotted on Dunwich
Heath, where there are animals grazing nearby and swathes of heather and
bracken, the Wicken Fen lizards in my photographs do not appear to have
ticks.
Much to my delight in this year when I have seen few ladybirds, we noticed two native 7-spots ...
I have added these to the
UK Ladybird Survey.
Unfortunately we also noticed this
Harlequin ... The thumb is to give a rough sense of scale.
We thoroughly enjoyed the chance to learn about some of the butterflies on the reserve, thanks to the knowledge and enthusiasm of Alison, a NT volunteer who leads butterfly walks.
We failed to see any Skippers this time, but we noticed a few
Small Tortoiseshells ...
... and quite a number of
Common Blues. These are exquisite little creatures.
I was keen to photograph a male and female Common Blue together, but had difficulty knowing where to focus the camera ...
We spotted a couple of
Brown Argus ...
... and
Speckled Woods.
We are now moving on to the insects that I find hard to identify with accuracy! Please leave a comment if you spot a mistake or can help with identification. There were good numbers of Hoverfly ...
I think the one above may be the
Striped hoverfly (Syrphidae).

| To be identified ... slightly different from the one above, perhaps a Sunfly? |
The breezy conditions probably accounted for the fact that there were few dragonfly on the wing. However, we found a few in the more sheltered spots. Here is a (?young)
Common Darter ...
... and another.
I think this may be a male
Ruddy Darter ... There seems to be a red tinge to the pterostigma.
There were several
spiders - my photos are as yet unidentified. Do let me know if you recognise these arachnids!
The creature below seems to be a
Short-winged Conehead (Conocephalus dorsalis), which is a species of Bush Cricket.
The photo below shows the length of the antennae!
I am guessing that this is
Roesel's Bush Cricket from the yellow markings ...
There were plenty of House Sparrows around the visitors' centre, but we saw surprisingly few birds on this occasion. We even failed to see a Marsh Harrier. However, the abundant insect life made up for any shortcomings on the avian front.
You may feel miles from nowhere (and indeed the nearest hostelry is called
the Five Miles From Anywhere No Hurry Inn), but you know for sure that you are on a nature reserve when you come across a reed with its own number!
There was one last surprise in store when we got back to the car ... I particularly love the pattern made by the creature's shadow!
