I think this is a Tiger Beetle or maybe a Searcher Beetle, it is a good bug that eats bad bugs.
I found it out in one of the pastures today it was running in a open place in the grass and its iridescent spots caught my eye. One way I attract these good beetles is by leaving wild places around our vegetable gardens. By doing this there is no need for pesticides even the so called "organic/natural" ones such as Pyrethrum. It is the most widely used "natural" pesticide and is derived from the chrysanthemum plant. There is another one called Organocide and is a mixture of 5% Sesame oil, 92% fish oil, and emulsifiers 3%. These sound sort of natural, what's wrong with them? There all from plants and animals. Well lets look at the chrysanthemum plant where was it grown? Were rain forests cut down, or some other ecosystem destroyed in order to plant a mono-crop of chrysanthemums to meet the world's demand for Pyrethrum? What about the Sesame oil? Was the Sesame grown sustainably? Or was it sprayed with Pyrethrum to kill the bad bugs! What about the fish oil? Fish certainly grow naturaly right? Well sadly maybe not these days. As the world's demand for fish goes up and there is no longer enough fish for every one in the ocean and lakes. We are starting to see more fish raised on fish farms. And the fish are eating a mostly corn (maize) diet. Fish eating corn? Yes they are breeding fish that can grow on corn more than likely GMO. Also the fish are fed antibiotics to keep them "healthy". So if you don't Want to support all this non earth friendly stuff, but still think you "need" to use something like Organocide. Why don't I make my own? Easy, just find some very Eco friendly Seseme oil and fish oil at the local health food store. What would be wrong with this? Nothing, you could eat it, its all food grade. But wait why do you think you "need" to spray this on your plants? Oh I have this little mite sucking the juice out of some of my plants and I read this will kill them. Well mites are related to spiders and so you may be killing them too. The spiders eat a lot of bad bugs and maybe mites too. So don't spray and let the good bugs kill the bad.
