very tiny bugs with 6 legs, blue heads, red back.there were about 50 of them huddle together. They stayed together until i got close enough to take picture then scattered. We have never had these in our area before and I have never seen anything like it before. These were found on our back porch. (Priceville, Al )
You have Fl predatory stink bugs or also called Halloween bugs on your porch. They are “good” bugs as they feed on other insect pests like caterpillars, leaf beetles and planthoppers. Both nymphs and adults feed on insects.
They are just found in the SE US.
They are known for their metallic blue/green thorax with red abdomens. The adults look similar.
The nymphs are known to congregate together…sometimes this is to work together on a food insect. Otherwise they sometimes are found together at night.
