I didn't check my pot plants in the Sunroom for 1 day and this is what I found! He had eaten just about every single flower on this geranium plant! Holes through the leaves too. I couldn't identify it even after a fair bit of googling but decided it couldn't be allowed to live.
@kali66 It could be, Kali - I looked at this but this one seems to have more colour. Though the description says a raised bump at the tail end which this one seems to have. Still, the fall army worm is an absolute pest so glad I ended its life.
