We were meant to be searching for frogs around a dam at Bambra but I got distracted by the beautiful little white moths flying around the rushes and grass.
They were Tipanaea patulella. Apparently the caterpillars bore into the stem of rushes.
PS I tried out something new for this blog - I uploaded the photo and comments from my Flickr page. It was easy peasy. (Except I see that the original photo title comes up in tiny font underneath the photo which I don't think is really necessary, and the tags didn't come across either.)
PPS And I've just discovered that when you click on the photo to view large it takes you straight to my Flickr page where you have to click on the 'All sizes' option.
