these red bugs with two? or three black spots and 6 black legs show up on my cactus in great numbers each year, now they are on my canteloupe and I kill them all three times a day. are they good, eating some other bug, or are they there to suck the water/juice out of my cactus and fruit? I also sometimes see little tiny ants around and wonder if these guys are there hunting smaller bugs. these are soft when mushed and not too fast and if knocked to the ground pretty much skitter away but you can mush them all b/c they don't fly and are not fast. would love to know if they are beneficial or not and what they are called. neem oil seems to make no difference.
