I found this egg sack today which belongs to the Wasp spider, a new comer to the UK and one which hasn’t to my knowledge been recorded at Cavenham Heath NR
The Wasp Spider is a very large, colourful spider that is a recent arrival in the UK from the continent and has slowly spread over the south of England. They build large orb webs in grassland and heathland, and attach their silk egg-sacs to the grasses. The web has a wide, white zig-zag strip running down the middle, known as a ‘stabilimentum’, the function of which is unclear. Mating is a dangerous game for males; they wait at the edge of the web until the female has moulted into a mature form, then take advantage of her jaws being soft and rush in to mate. However, many males still get eaten during this time.

Another venture to Cavenham Heath NR to spot some insects , yet again none found but did see another Adder

I found this fossil of what I think is a Micraster -Sea urchin which is about 83 million years old from the Upper Cretaceous period.
Found outside a rabbit burrow.
My first venture to Cavenham Heath Bug hunting , it was a frosty morning but blue skies and sunny. The Adder was sunning itself as you can see by the habitat photo it wasn’t easy to spot but I was on the look out for them as there were almost no insects. I saw one bumblebee and one beetle.
Very happy with the photos
Adders are the only venomous snakes found in Britain, although they are absent from Ireland. They use their venom to immobilise prey such as lizards, amphibians, nestlings and small mammals. After striking their prey, they leave the venom to take effect before following the victim’s scent to find the body. Although an adder’s venom poses little danger to a healthy adult human, the bite is very painful and requires urgent medical attention. Adders are the most northerly distributed snake and the only species found inside the Arctic circle.
