Jan. 14 (UPI) -- Even insects grow old before they die. Among mammals, birds, reptiles and even fish, the signs of aging are easily observed. The aging process is less visible among insects. But new research confirms even short-lived species, like field crickets, experience physical decline before they die. Scientists have previously observed aging among insects in the lab, but some researchers surmised their protection from the dangers of life in the wild allowed signs of senescence to surface. For the latest study -- published this week in the journal Evolution -- scientists observed field crickets in their natural environs, in the fields. Using more than 130 video cameras, researchers recorded and analyzed the movements and behaviors of several generations of field crickets over the co...
