Crane flies
These also have a common name of "daddy long legs" - and they have a habit of flying right at your head-torch at night, which is quite amusing to see grown men scream like a 7 year old girl.
Here they are otherwise occupied.
Now, I have heard some being so pregnant that they feel that they are going to burst...so I am not sure how this is happening, as the females eggs are bursting out at the moment of conception....hmmm
The first photo above is reproduced below, as i have turned this on its side for a better view.
