The delve closest to the AD Eastern Elsweyr Gate in Cyrodiil, Bloodmayne Cave. The entrance is at the bottom of the cliff, in case you've never been there.
The thunderbug respawn rate is unreal and for some reason the treasure chest rate, too. Not that in Cyrodiil there is typically anything good in chests, as the three "zone" sets are Cyrodiil's Ward, Cyrodiil's Light and Cyrodiil's Crest which are absurdly common and nothing you'd want to farm> Alliance motifs I guess.
