I like this species as they are beautyful, show interesting behaviour and can be observed year round on mild days at the food of Tilia trees (I have observations from almost all mobths, except August and November.. maybe my aim this year to fill this gap 
)
I did not know they are spreading abroad, which of course is a pitty… 
Will read this paper, thanks for the tip.
I mayself have neen heavily active IDing lycosidae in Texas to genus or species this week and will probably be busy with that for another week
