Alien in Bow?

Went outside to find some kind of stringy gelatinous snot dripping from the branches of my plum tree.

It was a bit like that scene - well any of those scenes - in Aliens where some unfortunate sod comes across some goo dripping from somewhere, spends a few moments poking it then looks up to be greeted with the jaws of the alien... and instant death.

I did look up (slowly) but saw nothing out of the ordinary (except for the goo of course). Pity the camera doesnt do macro too good.
