I think it's shed its skin, or is it prey?

The spider is one of the colour forms of Enoplognatha ovata. There does appear to be a cast spider skin there. |

That was quick, thank you! They do have such lovely patterning.

Let's not forget E. ovata's twin species, Enoplognatha latimana. The two cannot be distinguished from a photograph.

Evening Hed,
Yes, pretty spiders, these - vernacular name Candy-stripe Spider. Frits, I hadn't heard of latimana before, so thanks. How are they seperated? Palps, epigyne...
Take care, Jason  |

Genital research is necessary to distinguish between E. ovata and latimana, that much is certain, but since I don't have a microscope myself I haven´t looked into what features to look for. In fact, this is what makes me want to buy a microscope, so I can finally distinguish between spiders of the Enoplognatha, Philodromus, and Xysticus genera, to name but a few difficult ones.

Thanks Frits, you won't regret the investment! I currently have a 20x stereo model - just £35 from Amazon. I use an external light (12w halogen) since the built-in LED gives a short battery life and the switch is temperamental, but the optics are great.
I use it for Syrphids, Stratiomyids and Hymenopterans etc., but may go Xysticus/Araneus in the end... |

What more can I say? I probably can't link to the Amazon page, but run a search for 'Apex Examiner microscope'. Daylight should suffice for fieldwork, it stands about 9ins high when in-use, though this depends on what you have it focussed on (the eyepieces rise up when focussing on higher-up on taller objects), and has a 7cm working distance according to specs.
It's pretty much the entry-level model, so it doesn't have too many bells and whistles but does what it should, very well.
