Pelargonium highrise

This caterpillar seems to be living off this pelargonium.  He has been on it for most of the week and I can see he is chewing away at it.  I was hoping to close the computer at 5 and while I did get out and take the hounds for a romp it was not until 9.30 that I finished what I needed to do.   I need to do some more work over the weekend for something due Monday.  You will need to wish me luck on that!
