Wingspan?
On the water, the wings would be at rest against the body.
I was fishing near my hometown in S Central Mo. On a trout stream one summer day. I saw what I thought was a small bird hit the water. It was immediately taken by a large trout. After I got my wits about me, and realized it was a cicada, I searched my fly boxes for the largest fly I could find - a big 'ol hopper that was over-dressed. I plopped it out on the stream and immediately got a savage take.

There is no delicate presentation required. You just plop it out on the water and hold on.
