I wonder if he's looking at all the ant eggs that were in a flower pot I needed to put some young plants in.     
I'm feeling shattered today as I didn't get much sleep last night, Charlie was fidgety alternating with loud snoring, Luna and Arthur were excited with Luna's sleepover and wanted to carry on playing in the dark and there were the odd rumbles of thunder too.   I think an early night beckons.
In all we had 9mm of rain yesterday/overnight.
