Regular readers of The Naturephile may have noticed numerous references to the loopy weather we have experienced in this part of the world this year, in particular the wetness of the spring and the subsequent brevity of the summer. And you may also have cottoned on to the fact that I have a spider fascination.
Despite the unusual summer weather conditions, later on in the summer and into the autumn I found lots of spiders including two species which I haven’t seen here before. Common garden spider webs (Araneus diadematus) adorned every surface in my garden in the autumn and this particularly nice example was strung between two hawksbeard stems in the local meadow:

One of the most intricate webs I found was that of the labyrinth orb weaver (Agelena labyrinthica), they’re amazing constructions and most of them aren’t very visible until there’s a cold morning and the webs are laden with dew, then it’s possible to see that they adorn all the hedgrows and undergrowth.
The two species I found which I hadn’t seen before were the four spot orb weaver (Araneus quadratus) and the strawberry spider (Araneus alsine, aka orange wheel weaving spider).

Both my initial encounters with these little beauties were a little unnerving because I was unaware that spiders with these colours were lurking in my local undergrowth. The four spot flew past me at high speed when I snagged it’s trip line when I was trying to get in position to photograph a male common darter dragonfly:

And a strawberry spider dropped down a few centimetres from my eyes when I was unlocking my gate! All I saw was a bright red bulbous abdomen so my first thought was “Bloody hell, it’s a black widow!”. So I ran to get my camera before it disappeared. Both of these were females and around the same size as a regular garden spider, but as you can see the colours were very different.

Another spider I found in my garden this year was the missing sector spider (Zygiella x-notata). I was intrigued by the name of the missing sector spider and it transpires it comes from the design of the web. If the planar, circular web is a clockface, the part between 11 and 12 o’clock has no spiral threads, so is effectively a ‘missing sector’.

This particular individual was busy securing a cranefly and it seemed to take great pains to ensure the fly was maximally envenomated. It spent a couple of minutes running around the struggling fly, inflicting multiple bites before wrapping it up in a cocoon of silk and carrying it off to be hung from the window frame and consumed at leisure.
