My first guess without having the actual bug is that this little bug is a Tarantula Hawk species “Pepsis”. Tarantula Hawk wasp paralyze spiders and then lay eggs on them and the little baby wasp has something to eat. Morbid but that is life with bugs. They come with a BIG sting but rarely ever sting, I’ve heard they have the second most painful sting in the world.
Steer clear of these wasps and let them have access to all the spiders out there.
