This
fossil amber contains an unusual assemblage of what are commonly
termed “wireworms”, grubs of beetles of the Family Elateridae,
or Click Beetles. These larvae pass a long life (two or three years)
in the soil, feeding on the roots of plants, and they often cause
much damage to farm crops of all kinds, but especially to cereals.
Wireworms are known by their broad heads and cylindrical or somewhat
flattened bodies. The three pairs of legs on the thoracic segments
are short and the last abdominal segment is, as is frequently the
case in beetle grubs, directed downwards to serve as a terminal
proleg.
