A parent bug, Elasmucha grisea (Hemiptera: Acanthosomatidae), with eggs on the underside of a birch leaf. This species got its common name because it protects its young before and after they have hatched. I followed this individual for several days but, sadly, it and the eggs disappeared before they hatched out. Maybe a bird found it.
