Whatever they are they didn't seem to bother the Black Caps who dominated the second half of the day taking eight Indian wickets for 123 runs.

Earlier this year a swarm of bees put the Black Caps on the back foot in a bizarre incident in their tour match in Harare. During day two of their match against Zimbabwe A, a swarm of bees buzzed over the Harare Sports Club and forced the players to hit the deck in search of cover.
Allrounder Mitchell Santner said it was the first time he had seen anything like it while playing cricket, but downplayed the threat the bees posed.
"I saw Boulty [Trent Boult] hit the deck pretty early, from there everyone else seemed to hit the deck. I was the only one standing, I think you'll find," he said.
"They were quite far away, so I don't know why everyone was on the ground."
