This little animal is eating my vegetable garden. Can someone please tell me what it is and how to get rid of it? Thank you

Can you get a clearer picture? The last one is clear but it looks like it has been squashed. Is it the same as the bug in the first three? Is the red stuff on the finger blood? If so have you actually seen them eating the plants, and can you show a picture of the damage?

It is unfortunately very out of focus, but it looks to me like a Tabanus nigrovittatus (Greenhead horsefly).

That does look like a possibility and would account for what looks like blood. In that case it would not be what's eating the plants.
