Psorosina hammondi

Riley, 1872

Appleleaf Skeletonizer

Psorosina hammondi is a pyralid in the Phycitinae, commonly known as the Appleleaf Skeletonizer. The was described by Riley in 1872 and is notable for its specialized larval feeding on hawthorn (Crataegus) leaves, producing characteristic skeletonizing damage. Despite its distinctive and association, detailed biological information remains limited in accessible literature.

Identification

The is most readily identified by its association with Crataegus (hawthorn) and the distinctive skeletonizing feeding damage produced by its larvae. may be attracted to lights. Specific morphological characters distinguishing P. hammondi from other Phycitinae species are not documented in the available sources.

Appearance

As a pyralid , likely possess the typical characteristics including scaled wings, a slender body, and thread-like or slightly feathered . The "Appleleaf Skeletonizer" suggests larvae are the more conspicuous life stage, though specific morphological descriptions of either larvae or adults are not readily available in the provided sources.

Diet

Larvae feed on Crataegus (hawthorn) leaves, consuming tissue between the leaf and producing characteristic skeletonizing damage.

Host Associations

Crataegus - larval food planthawthorn

Behavior

Larvae exhibit skeletonizing feeding , consuming leaf tissue between while leaving the vascular network intact. This produces a characteristic lace-like appearance on damaged leaves.

Human Relevance

The "Appleleaf Skeletonizer" suggests potential relevance to apple , though the primary documented is hawthorn (Crataegus). The may be of minor concern as a foliar pest.

Similar Taxa

Other Phycitinae speciesMany pyralid moths share similar ; accurate identification requires examination of genitalia or association with specific plants and larval feeding damage patterns.
