I have three images for you that I was hoping to get confirmation on. I know the flat brown bug is a stink bug however what I don\'t know is if it is the Brown marmorated stink bug that is an invasive species. The caterpillar is a Northern Sphinx moth caterpillar I believe from what I\'ve been able to find and lastly the grasshopper. All I know is its a grasshopper but I\'ve never seen one with such long antenna before.
Thanks again for any and all help. It\'s been a great summer for bugs.
