Fish and Insect Fossils from the McAbee Deposit Many of the leaf fossils also show evidence of insect activity, such as feeding, plant parasitism, and egg laying activities. A couple of examples are shown below. The photo on the left shows a serpentine mine on a beech leaf caused by insect feeding, and the leaf on the right shows possible egg-laying activities. Similar egg scars on leaves from Republic, Washington have been attributed to flea beetles (Lewis, 1992).
