p. 87 More specifically, the pictured blepharicerid pupae belong to a Blepharicera species.
p. 88 Correction: The aphid exuviae shown here do not belong to Hormaphis hamamelidis. The aphid in question was the same species as this one, a member of the subfamily Calaphidinae (possibly Euceraphis).
p. 102 The pictured tachinid puparia belong to the subfamily Exoristinae. One of the adult flies that emerged is pictured here.
