From smallwonders: "Marsh Crane Fly - Native to Europe and was probably introduced to North America via infested soil media. The larvae, known as leatherjackets, feed on roots & crowns of turf grass & can be problematic. This feeding can cause patches of lawn and turf to die leaving bare soil. Grand Rapids, MI Zone 5b"
Runner Up with 145 points:
From smallwonders: "Tachinid Fly (C. concinnata) - Native to Europe, this tachinid was introduced to the U.S. as a biological control of gypsy moths. This introduction has failed due to the fact that this fly has over 200 host species & has attacked many native species, including threatened ones.(i.e. - Giant Silk moth) Grand Rapids, MI Zone 5b"

From DaylilySLP: "Japanese beetles (Popillia japonica) Japanese beetles munching away.

From mygardens: "This Northern Mole Cricket is generally not found in colder areas such as this zone 6b, New York. However, with the global warming, it eats the roots of our plants and has made it impossible to grow vegetables in our vegetable garden. We have to plant in large pots & stuff fine netting in the holes."

From dragonfly62: "This is a "Dragonfly" which can be invasive is some areas. We are in zone 5."
