Apples damaged by European earwig

Apples damaged by European earwig

The European earwig (Forficula auricularia) has been incorrectly associated with apple damage. Stem bowl splits (a) are a horticultural issue; though these splits are sometimes chewed on by earwigs (b, upper arrow) and sheltered in by earwigs (b, lower arrow). Earwigs have been observed to cause damage to apples during laboratory confinement, but field studies have shown no correlation between fruit damage and earwig densities.
