Hi. I just found your site… fascinating! When I lived in north Texas, I took pics of two bugs that I never was able to identify. Maybe you can? The big green bug (katydid or grasshopper?) was spotted in late February when the bugs are just waking up, so I suspect it’s pretty young.
It is difficult to be certain due to the angle, but this looks like a Cone-Head, a group of Katydids in the genus Neoconocephalus. The other photo is of an immature Hemipteran.
