Crisicoccus taxodii
Bald Cypress Mealybug
Crisicoccus taxodii is a mealybug species in the family Pseudococcidae that feeds on bald cypress (Taxodium distichum). It is one of several mealybug species associated with conifers in this genus. The species was described by Kosztarab in 1996 and has been documented in the United States.
Dioryctria caesirufella
Dioryctria caesirufella is a snout moth in the family Pyralidae, described from Texas in 1983. The species exhibits sexual dimorphism in forewing length. Its forewings display a distinctive bluish-grey ground color with reddish dusting. The larval host plant is possibly bald cypress (Taxodium distichum), though this association requires confirmation.
Dioryctria pygmaeella
baldcypress coneworm moth, cypress coneworm moth
Dioryctria pygmaeella is a snout moth in the family Pyralidae, described by Émile Louis Ragonot in 1887. The species is restricted to the coastal plains of the eastern United States and eastern Texas. Larvae feed within the cones of baldcypress (Taxodium distichum) and pondcypress (Taxodium ascendens). The species completes up to three generations annually.
Eudociminus
pine weevils
Eudociminus is a genus of weevils (Coleoptera: Curculionidae) containing at least two described species. The genus includes the cypress weevil, Eudociminus mannerheimii, which is native to North America and associated with cypress trees. Published biological information for the genus is extremely limited.
Eudociminus mannerheimii
Cypress Weevil
Eudociminus mannerheimii, the cypress weevil, is a native North American beetle in the family Curculionidae. It breeds primarily in scarred, weakened, or fallen cypress trees and occasionally damages nursery stock and stump sprouts. Despite its potential to cause localized tree mortality, published biological information remains extremely limited.
Iridopsis pergracilis
cypress looper moth, Cypress Gray
Iridopsis pergracilis, commonly known as the cypress looper moth or Cypress Gray, is a geometrid moth species described by George Duryea Hulst in 1900. The species occurs in the eastern United States from Maryland to Florida. Adults have a wingspan of 26–28 mm. The larvae are specialized feeders on Taxodium distichum (bald cypress), including the variety T. distichum var. nutans.
Isoparce cupressi
Cypress Sphinx, Baldcypress Sphinx
Isoparce cupressi is a sphinx moth (family Sphingidae) commonly known as the cypress sphinx or baldcypress sphinx. The species is strongly associated with cypress swamp habitats in the southeastern and south-central United States. Adults are active from February through October in the southern portion of their range, with multiple generations per year reported. The specific epithet 'cupressi' references the genus Taxodium (bald cypress), indicating a close ecological relationship with this host plant.
Taxodiomyia
cypress gall midges
Taxodiomyia is a genus of gall midges in the family Cecidomyiidae that induce galls on cypress trees (Taxodium spp.). The genus contains at least three described species, all specialized to form distinctive twig or leaf galls on their coniferous hosts. These tiny flies are rarely observed directly, with their presence most commonly detected through the abnormal plant growths they induce.
Taxodiomyia cupressi
Cypress Twig Gall Midge, Cypress Flower Gall Midge
Taxodiomyia cupressi is a gall midge (Diptera: Cecidomyiidae) that induces distinctive twig galls on cypress trees (Taxodium spp.). The species forms spongy, globular galls on new growth that are initially snow-white and turn brown with age. It has been documented in central Illinois and Missouri, with observations on cultivated bald cypress outside its native range. The midge undergoes complete metamorphosis with multiple generations per year, overwintering as larvae within fallen galls.

cypress twig gall midge
A gall midge in the family Cecidomyiidae that induces distinctive twig galls on cypress trees. The spongy galls are initially snow-white, turning brown with age, and eventually drop from the tree with leaf fall. Larvae pupate within the galls, with adults emerging later in the season or following spring. The species is considered a pest of ornamental and native cypress plantings.
Taxodiomyia taxodii
cypress leaf gall midge, cypress twig gall midge
A gall midge species in the family Cecidomyiidae that induces distinctive galls on cypress trees. Adults are tiny flies that lay eggs in cypress tissues, with larvae developing inside spongy, globular galls that initially appear snow-white and turn brown with age. The species is closely related to Taxodiomyia cupressiananassa, which produces similar galls on bald cypress.
Urocerus taxodii
Taxodium horntail
Urocerus taxodii is a species of woodwasp in the family Siricidae, described by Ashmead in 1904. As a member of the genus Urocerus, it shares the characteristic elongated, cylindrical body form and prominent cornus (horn-like projection at the abdomen tip) typical of horntails. The species is associated with Taxodium (cypress/bald cypress) as a larval host, as indicated by its specific epithet. Like other siricids, females possess a long ovipositor for drilling into wood to deposit eggs, and they vector wood-decaying fungi that serve as food for their larvae.
