I was going to say this is a grasshopper, and therefore similar to a locust, but its possible to the Hebrew of the time, they would not know the difference.

So I looked up the explanation of a locust being kosher, and it turns out not all are. They had a list of four colored locust species which are admissible, but knowing which ones are okay is nearly impossible. They apparently have gone two ways on this. The first, which is followed by most Ashkenazic Orthodox Jews, is to just forbid all locusts to avoid mistakes. The second, The Halachah or final ruling, allow locust eating if there is a continuous tradition, which can be based on the family or the location. I thought this was pretty interesting. en.wikipedia.org/wiki/Kosher_locust Also the Wiki says they might have been pickled for eating.
