Agrilus crataegi
hawthorn agrilus
Agrilus crataegi is a species of metallic wood-boring beetle in the family Buprestidae. The species was described by Frost in 1912 and is found in North America. The common name "hawthorn agrilus" suggests an association with hawthorn (Crataegus), though specific biological details remain poorly documented. Like other members of the genus Agrilus, it is presumed to have larval development in woody plant tissue.
Balsa tristrigella
Three-lined Balsa Moth
Balsa tristrigella, commonly known as the Three-lined Balsa Moth, is a small noctuid moth native to eastern North America. Adults are active from May through August and are characterized by their modest wingspan of 25–30 mm. The species was originally described by Francis Walker in 1866 under the name Garzana tristrigella before being transferred to the genus Balsa. The larval stage feeds specifically on hawthorns (Crataegus species), establishing a clear host-plant relationship with this genus of shrubs and small trees.
Blaesodiplosis
Blaesodiplosis is a genus of gall midges in the family Cecidomyiidae, established by Gagné in 1973. The genus contains at least four described species, including species associated with hawthorn (Crataegus). Like other gall midges, members of this genus are presumed to induce gall formation on host plants, though specific biological details remain limited.
Carposina fernaldana
Currant Fruitworm Moth
Carposina fernaldana is a small moth in the family Carposinidae, described by August Busck in 1907. The species is named in honor of Charles H. Fernald. It occurs in eastern North America from Quebec southward along the Mississippi drainage to Missouri. The larvae feed internally in fruits of hawthorn (Crataegus) and currant/gooseberry (Ribes) species.
Conotrachelus crataegi
quince curculio, Hawthorn Curculio
Conotrachelus crataegi, commonly known as the quince curculio or hawthorn curculio, is a true weevil (Curculionidae) that infests hawthorn fruits (Crataegus spp.) in North America and Mexico. Adults are attracted to fruit volatiles, and females oviposit into developing fruits where larvae bore through flesh to destroy seeds. The species exhibits overlapping developmental stages with adults active primarily from April to September. It is a significant pest of commercial hawthorn (tejocote) production, causing direct damage through larval feeding and indirect losses via premature fruit abortion.
Coptotriche malifoliella
Appleleaf Trumpet Miner
A small moth in the family Tischeriidae known for its distinctive larval leaf-mining behavior on apple and hawthorn. The species was described from North America in 1860 and is recognized by the common name Appleleaf Trumpet Miner, referring to the trumpet-shaped mines created by larvae.
Dasineura crataegibedeguar
hawthorn button-top gall midge
Dasineura crataegibedeguar is a gall midge in the family Cecidomyiidae that induces distinctive galls on hawthorns (Crataegus spp.). The species is known for forming button-top or bedeguar-like galls on host plant tissues. Like other Dasineura species, it has a complex life cycle involving gall induction and larval development within plant tissue. The species was originally described by Osten Sacken in 1878 and has undergone taxonomic revision, with some authorities placing it in the genus Blaesodiplosis.
Parornix inusitatumella
Parornix inusitatumella is a leaf-mining moth in the family Gracillariidae, native to eastern North America. Its larvae feed on hawthorn species (Crataegus), creating distinctive blotch mines on leaves. The species has been documented across multiple Canadian provinces and several U.S. states in the Great Lakes and northeastern regions.
Psorosina hammondi
Appleleaf Skeletonizer
Psorosina hammondi is a pyralid moth in the subfamily Phycitinae, commonly known as the Appleleaf Skeletonizer. The species was described by Riley in 1872 and is notable for its specialized larval feeding behavior on hawthorn (Crataegus) leaves, producing characteristic skeletonizing damage. Despite its distinctive common name and host association, detailed biological information remains limited in accessible literature.
Utamphorophora crataegi
Four-spotted Hawthorn Aphid
Utamphorophora crataegi is an aphid species in the family Aphididae, commonly known as the Four-spotted Hawthorn Aphid. The species was originally described as Amphorophora crataegi by Monell in 1879 and later transferred to the genus Utamphorophora. It is associated with hawthorn (Crataegus) as a host plant, as indicated by its specific epithet. The species has been recorded in Hawaii and the conterminous United States.
