Problems with ID

Can anybody help identify this species

and an entire plant

Howard,
I can do this - its Rumex vesicarius - a member of the dock family. It is quite widespread and known from Bahrain. The leaves make a pleasant rather sour salad snack.
Cheers Mike Jennings

and this caterpillar - most probably a large moth - first the eating end

the rear end

Could be a 'humming bird' type - many of the hawk moths hover at flowers to feed - amongst the species which sometimes migrate to the UK, your specimen somewhat resembles the caterpillar of the spurge hawk moth, scientific name: Hyles (= Celerio) euphorbiae, and related species belonging to the same genus, Hyles (= Celerio).
