This is an Ambush bug, one of the True bugs. And I believe most of these in the yard are in the genus Phymata. Very space age. And those are mantid type graspers to the right of those vicious looking eyes. There must be several species of these and they seem to favor Eupatorium and Solidago for their hideouts.

Ambush bug of the goldenrod camo variety. With a large Tachinid fly capture. You can, with care, see the bug's face, feeder tube, legs and thorax in its perfect color hideaway.
 
Ambush day was this day in Cleburne county in 2015. And Black-eyed Susans were the danger flower for any butterfly to land on. Here a Buckeye is lost in the world to make more Ambush bugs. 
 
Clouded Skipper chose the wrong perch on my butterfly bush in 2020.   
Ambush in wait among the 2020 chives. May be Phymata americana. 
 
Ambush of the spinier variety. Look like little dragons to me. This is a Sinea species, possibly spinipes. Or diadema. I became a bit obsessed watching this thing grow while it stayed on this one flower bloom for weeks. Then I lost it. I never caught it with a capture. Though I saw it staring down some butterflies a few times.  I
Different day, same flower. Can't remember if it was older or younger here. Dragon staredown.
Dragon aging into more spininess. Back view not any kinder looking. Armored for attack from the rear apparently. Same damn Susan.  

The Hemipteran order is large. Many families. This is a member of the Coreidae group, otherwise known as the leaf-footed bugs. Leptoglossus phyllopus is the name of this common one. There are about 80 members of the family in North America. There are seven members of this genus. None of the others have this complete light line across the back. They are mostly plant feeders and sometimes this involves some of our garden plant species. This one specializes in Cirsium, or thistle, species, but in Florida it loves to fly over to the nearby orange groves and suck young orange tree buds. Naughty, naughty.
This is likely the same insect. They gather on my Yucca stalks when they do bloom in spring. Sometimes 20 or 30 of them. You can see the 'leaf-foot' well here. This is in 2020.  
This one was posing so well in Camp in 2020 I shot it again. Same species on a fine grass head in late summer.  
This appears to be a younger Leaf footed species. Not sure if this is a juvenile Leptoglossus at this time. From 2020.  

This is likely a close relation of the above. Perhaps even Leptoglossus again. Swarmed on my Yucca bloom stalk. Breeding and interacting even after most of the blooms were gone.
 
This is a Reduvid and likely Apiomeris crassipes. Somewhat variable in bugguide. It is something close if not.  
This pair of an unknown genera feeding on the beautyberries. I just like macro beauty berries really.  
Another Reduvid and this one is in the genus Pselliopus. Most likely P. barberi. I found several over my property in 2020 in various age stages. Always zebra legged and alert.   
Another Pselliopus over near the swamp in 2020.
 

This monster with the orange tips to the antenna is Acanthocephala terminalis, it is another Leaf-footed Bug. I have had them buzz up to me from nearby plants. This one was just giving me the careful stare. This is one of the largest species in this group.

I have not really been paying attention to Aphids, which, of course, are also a form of true bug that are plant eaters. And can be pests on crops and flowers. In 2020, I have now noted aphids in many colors. Apparently they can be very plant specific. These bright green guys were on a tower of a Goldenrod stem. I have also seen yellow, black and red species. All on different plants.

Aphids of the black persuasion. I don't know how many species are out there. Bugguide says 1400 in our area. That may mean North America. Only with the new camera could I even hope to capture these tiny things. Can be plant specific and apparently some species do come in multiple color forms and even change plants in mid life cycle. Unusual things. They can be pests on crops and gardens. We will pay more attention.   
Aphids of the yellow form on Ironweed. With attendant ants.  
And aphids of the red variety. On an unidentified weed in the front beds on Round Mountain in 2020. (Also new cam with copy mark error.)  
 
Aphid traffic on the back porch plants. Visible all summer in 2020.   
Aphids feed the world. I suppose. Sometimes these beasts just want the honeydew the aphids produce.   
Ants and Aphids have quite a few complex relationships out there. This appeared to be some tending on another color spectrum of aphid.
