ARACHNIDA > ARANEAE > Araneidae > Araniella

Following on from the previous account regarding the Araneus species, this page features the second largest genus Araniella, which includes five species that are collectively known as 'cucumber spiders' due to their bright, apple-green abdomens.

The two common species Araniella cucurbitina and Araniella opisthographa are said to be indistinguishable in terms of general appearance and size, although the actual description of the former refers to a conspicuous red spot immediately above the spinnerets that is only visible from the underside. Interestingly, the first individual I photographed had a red spot and, consequently, I labelled it as Araniella cucurbitina based on this information. I've never bothered to change the identity and have deliberately included the photo here at the end of the sequence for reference, even though I've since been told that the red spot isn't necessarily diagnostic of that particular species. As advised, I'm now labelling all individuals simply as Araniella sp.  

I think they're rather smart-looking little spiders with their large glossy, yellow-brown carapace and apple-green abdomen. The male is easily distinguished by the broad black marginal bands around the carapace, and his black palps and black leg rings. The one I photographed at Garston Wood had multi-coloured legs, which was interesting. I tried to find out whether the red bands had any significance, perhaps indicating that it was a different form or one of the less common species, but unfortunately, I couldn't find any relevant information. Females are much plainer by comparison, and I was surprised to find that I've only photographed one as all the others I've seen have been males.

They occur in a variety of habitats including woodland, along hedgerows and in gardens where they may be found on bushes or trees. The best time to see them is during May and June when they are at their most active.

The remaining three species are rare and can effectively be disregarded, although from the distribution maps it's not inconceivable that I might find Araniella inconspicua, which would be good except that there would be no way of knowing without microscopic examination! It occurs mostly on trees, especially oak and pine, but the aforementioned species may also be found on trees, particularly oak, so even the habitat wouldn't be an indicator of something different.
