CENTRAL FLORIDA CRITTER OF THE DAY: Stink Bug (Thyanta perditor)
One of the Red shouldered stink bugs which can be pests since they suck juices from plants.
There are many different species of stink bugs and they can be difficult to identify, but the red shoulders with points and speckled wings lead me to this species.
Shown on Florida Native Plant: Spanish Needles (Bidens alba)
Stink bugs are eaten by spiders and the freeloader flies will latch on to feast as well.
