Wasp Spider

 I first came across a female Wasp Spider (Argiope bruennichi) on the Isle of Wight, back in the early 1990's. In those days it was a rare find but nowadays it is a common species in southern England.

There is no mistaking this stunning creature for any other species of spider and whilst many of us shudder at the sight of a house spider galloping across the living room carpet, I have no qualms about getting close to this beauty.

Not only is the spider itself easily identified but its web is also very distinctive, usually bearing one or more zig-zag features in its structure.

The peak of the Wasp Spiders breeding season occurs during August when sometimes many females can be found sitting in the middle of their webs, low down in long grass.

It is often said that every picture tells a story and that is certainly true of the following image. 

Approaching the female Wasp Spider is rather hazardous for the much smaller male. The female regularly eats the male either after or during mating and he must choose his moment carefully if he is to escape after a successful mating. That moment is generally just after the female has shed her old skin and before her new skin and mouthparts have hardened.

In the following image, the shed skin of the female can be seen in the web above her. Above that, a male spider sits at the periphery of the web contemplating his approach.

On the left of the female are the remains of another spider that she has devoured. This was either an unsuccessful male or another species of spider that wandered too close.





This male awaits his chance to approach a female on another web.





This female is feeding on a grasshopper (their main prey) that has leapt into her web.





The flask shaped egg sac of the Wasp Spider can be quite variable in size but the following image is of the largest one I have ever found, measuring 4cms. in length.

The Gatekeeper

 The Gatekeeper (Pyronia tithonus) is one of our commonest butterfly species but is no less attractive for that. It can be found across a range of  habitats including downland, woodland and field margins during July and August. It is very common in my local wealden woods.

Damselfly Encounters

With little shelter from the hot sunshine beating down, I have not ventured onto Pevensey Levels in the last week or so but have sought the shade and coolness of some favourite riverbanks and Wealden ponds in search of damselflies. 
 
The White-legged Damselfly (Platycnemis pennipes) is a localised species in Sussex but often abundant in favoured habitats. Whilst walking along an East Sussex riverbank this week, I disturbed dozens of this attractive and distinctive species.

This recent colonist from Europe is now a widespread species in south-east England.

During Autumn 2017, I found dozens of egg sacs of the Wasp Spider (Argiope bruennichi) in a Wealden woodland clearing. I returned to the site last week to look for adult females on their webs. These striking spiders make a distinctive web with zig-zag 'sutures' within the structure.

Marvel of the Day

The moth catch on Friday morning reflected the season with autumnal species becoming more prevalent. The best of the bunch was the stunning and aptly named Merveille du Jour (Dichonia aprilina), one of the most attractive of the Noctuid moths.

The butterfly of the moment is certainly the Red Admiral which is currently appearing in good numbers on Pevensey Levels as they start to head south.

Red Admiral (Vanessa atalanta)



On Wednesday, Bob and I headed to Rye Levels to see whether we could find any interesting Odonata such as Red-veined Darters and Willow Emerald Damselflies, both recent colonists to Southern England from the continental mainland...no such luck. I found a late season female Wasp Spider (Argiope bruennichi) and a little later an egg sac for this species, secreted in the undergrowth. I also took some photographs of what I thought were two different species of spider but on later checking my books I realised that they were different colour forms of the same species; Araneus quadratus.
