Thanks. I completely missed T. versicolor when I was looking through the Tetragnatha page!

How do go about telling T. versicolor from, say, T. elongata? I'm still very inexperienced and was trying to figure it out just now from the images on their respective pages. I noticed the ventral markings and coloration looked more similar with T. versicolour, but there seems to be a lot of variation so I'm not sure if this is reliable.
