Where there was once Ladybirds now a Spider

On an earlier picture I managed to snap a group of ladybirds together.
This morning on the same electric fence pole there is now a spider building a web.
If you also look hard enough to the right you will see an incredible stupid fly that appeared just to be waiting for the web to be build to commit some sort of fly suicide.
(Later on in the afternoon the web was complete and a small fly shape package in the corner).
