I found these in my yard yesterday, I've never seen them before and don't know what they are or if they're harmful. Thanks,

Hello Tassos,

That is an assassin by nymph. It’s either a spined assassin bug, Sinea diadema (Reduviidae) or the closely related spiny assassin bug, Sinea spinipes (Reduviidae).
