Daddy or Mummy Longlegs?

I snapped this Crane Fly on a window.  He was outside and I was inside.  You can see that HE is a DADDY Longlegs because the end of his body is square.  The females have a pointed abdomen so that they can push their eggs into the grass roots where their larvae, called leatherjackets will feed all summer.

The adults emerge from the ground in September and drift about looking for mates.

As they are flies they only have two wings.  You can see that the second pair of wings, which most insects have, have developed into balance organs called halteres.  They look like tiny drumsticks on crane flies but don't show up quite so well on other flies, although they nearly all have them.
