Antispila aurirubra
Antispila aurirubra is a small North American moth in the family Heliozelidae, described by Annette Frances Braun in 1915. It is endemic to California and is associated with Cornus (dogwood) species as larval hosts. The species exhibits distinctive metallic coloration on the thorax and forewings.
Antispila freemani
Antispila freemani is a small moth in the family Heliozelidae, described by J. Donald Lafontaine in 1973. It is native to North America, with records from Ontario, British Columbia, and Vermont. The larvae are leaf miners that feed specifically on Cornus canadensis (bunchberry).
Calligrapha philadelphica
Dogwood Leaf Beetle, dogwood calligrapha
Calligrapha philadelphica is a leaf beetle in the family Chrysomelidae. It is known by the common names dogwood leaf beetle and dogwood calligrapha. The species is found in North America, with records from Canada and the United States. Like other members of the genus Calligrapha, it is associated with dogwood (Cornus spp.) as its host plant.
Craneiobia
Craneiobia is a genus of gall midges in the family Cecidomyiidae, established by Kieffer in 1913. The genus contains at least two described species that induce distinctive tube-like galls on leaves of Cornus (dogwood) plants. These insects are specialized gall-formers with a narrow host association.
Craneiobia tuba
Craneiobia tuba is a gall midge in the family Cecidomyiidae that induces distinctive cylindrical galls on dogwood leaves. The species is known from four host plants in the genus Cornus. Adults emerge in spring to lay eggs on unfolding leaves, with galls developing by summer. Larvae complete development in fall, then overwinter underground in cocoons.
Epinotia lindana
Diamondback Epinotia Moth
A small tortricid moth with a wingspan of approximately 17 mm. The species occurs across northern and eastern North America, with larvae feeding on Cornus (dogwood) species. Adults are active during the warmer months. The common name refers to the distinctive wing pattern.
Eudeilinia herminiata
Northern Eudeilinia, Northern Eudeilinia Moth
Eudeilinia herminiata is a North American hook-tip moth in the family Drepanidae, described by Guenée in 1857. It ranges across much of the continent from British Columbia to Newfoundland, south to Florida and Texas. The species is associated with deciduous woodland habitats and has a single annual generation with adults active from spring through late summer.
Euthyatira pudens
dogwood thyatirid moth, peach-blossom moth
Euthyatira pudens is a medium-sized moth in the family Drepanidae, commonly known as the dogwood thyatirid moth or peach-blossom moth. First described by Guenée in 1852, this species occurs across much of North America from southern Canada to the Gulf of Mexico. It is strongly associated with moist forest habitats and riparian corridors. The larvae feed exclusively on Cornus (dogwood) species.
Molorchus bimaculatus semiustus
A small longhorned beetle subspecies in the ant-mimic genus Molorchus, occurring in North America during early spring. Adults have been observed on flowers of various flowering trees, particularly flowering dogwood (Cornus florida). The genus exhibits Batesian mimicry of ants, with adults resembling small ants in size and form. This subspecies is part of a complex of ant-mimicking cerambycids that frequent blossoms.
Oberea tripunctata
dogwood twig borer
Oberea tripunctata, commonly known as the dogwood twig borer, is a species of longhorn beetle in the family Cerambycidae. Adults emerge in early June and feed on dogwood twigs, causing girdling damage. Females lay eggs singly on healthy twigs; larvae bore into twigs and overwinter in stems, with some individuals taking up to two years to complete development. The species is considered a minor pest of flowering dogwood and has been recorded from additional hosts including elm, azalea, viburnum, and various fruit trees.
Pseudasiphonaphis corni
Waxy Dogwood Aphid
Pseudasiphonaphis corni, commonly known as the Waxy Dogwood Aphid, is an aphid species in the family Aphididae. It belongs to the tribe Rhopalosiphina within the subfamily Aphidinae. The species was described by Tissot in 1929. As a member of the genus Pseudasiphonaphis, it is part of a group of aphids associated with specific host plants.
