I wouldn’t be surprised if they are full of protein & one of the insects future generations will be eating as a staple.
I watched an episode of The Americas with Simon Reeve last night. He tucked into a feed of fried crickets in Mexico. He reckoned they were beautiful & crunchy.
I have a recipe for cockroaches if interested. You eat them like artichoke leaves - hold them by the wings from the back, put it head first between your teeth without biting, then pull and scrape all the “protein” with your bottom incisors. Yum…
