I have no clue what this bug is. It has 8 legs, but two of them it seems to use as antennae, so I don’t think it’s a spider….do you know what it is?
You have a species of immature Assassin Bug. You are very lucky you did not get bitten. Even the nymphs can deliver a painful bite. In addition to its sucking mouthparts, it has six legs like all insects, and two antennae.
