Found on Solidago canadensis with prey. I don’t think I can identify they prey species but it looks similar to the bee mimic hoverflies that I see around. I found another wasp looking insect on the same goldenrod plant wrapped up in a similar manner with no spider visible nearby.

I'm not familiar with spiders, so this is probably a wrong ID, but the specimen closely resembled a description of Enoplognatha ovata. I observed this spider (not a crab spider) stalk a housefly, then attack it, move back and wait, but it used silk to restrict the fly's movement before feeding on it.
