Cilantro

I just washed and checked a bunch of cilantro using the thrip cloth method as taught to me by one of the members of jsor a few ears ago. The thrip cloth test showed up clean, but as I was chopping the cilantro I saw a big green bug that might be a grasshopper. Do I throw the batch out? Rewash? It could’ve never came through the strainers to show up on the thrip cloth. What’s the protocol with something like this?
