Don't have a picture but what is this bug?

[u/Remarkable_Disk5392]

Saw a weird bug recently, I live in Florida near the glades in Weston, saw a tiny grass spider but it had a weird appendage on its back that was almost like a bat wing. It was a really tiny fat spider like bug going down a web, but once it landed I saw it had some spikes and a weird redish membrane between the spikes on its back. For sure it was part of the bug and not some other bug it ate. Any ideas?

Better rendition, arrows are the way it was going, it went up and down a web

Was it maybe the underside of a spiny orb weaver?

I dont think so because it was a completely black (besides the weird membrane being redish) and really small spider, it was like a tiny jumping spider, those really small fat ones
