Found this little guy jumping around my plants today. Such smart little critters. I watched him for a while and he was slowly walking around looking for bugs and whenever I moved to look at him he would turn and look at me (like in the pic). If he starts building webs I'll toss him outside. Seriously tho, beneficial insects are great in certain situations. Spider mite predators, fungus gnat predators, ladybugs, even praying mantis. There are many more. Sometimes if a plant is too far infested, no amount of beneficials will catch up to the population to make a difference.
