With its sleek, dark body and finely ribbed brown wings blanketed in microscopic gray hairs, this elegant beetle is a true master of transformation. It spends the first two years of its life hidden beneath the soil as a slender, tough-skinned larva. Known to farmers and gardeners as a &#8220;wireworm,&#8221; it spends this subterranean phase feeding on plant roots and tubers. Once it emerges into the summer sun as an adult, however, its destructive underground days are over. Transitioning into a beneficial pollinator, it takes to the air to patrol meadows and woodland edges, dining instead on pollen, sweet nectar, and the occasional small insect. I crossed paths with this striking click beetle in several forested areas during my long-distance bicycle tour across Sweden and Finland.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Meet the
