Asphondylia apicata
Creosote Apex Gall Midge
Asphondylia apicata is a gall midge species in the family Cecidomyiidae, first described by Gagné in 1990. Like other members of its genus, it induces distinctive galls on host plants through a poorly understood mechanism involving chemical manipulation of plant hormones. The genus Asphondylia is notable for inducing galls on creosote bush (Larrea tridentata) and other plants, with multiple species often specializing on a single host species. The specific epithet "apicata" refers to the apex or tip of plant structures where galls may form.
Asphondylia auripila
Large Creosote Gall Midge
Asphondylia auripila is a gall midge in the family Cecidomyiidae that induces stem galls on creosote bush (Larrea tridentata). It is part of a species group of 15 closely related Asphondylia species that have partitioned creosote bush ecologically, with different species inhabiting leaves, stems, buds, and flowers. A. auripila specifically occupies the stems, forming distinctive pom-pom-like galls. The larvae develop within these plant-generated structures, which provide both shelter and nutrition.
Asphondylia diervillae
Asphondylia diervillae is a gall midge in the family Cecidomyiidae. It is one of approximately 15 species of Asphondylia flies that induce galls on creosote bush (Larrea tridentata) in the southwestern United States and Mexico. The larvae develop within plant tissue, manipulating host plant development to form protective galls.
Asphondylia florea
Creosote Flower Gall Midge
Asphondylia resinosa
Creosote Resin Gall Midge
Asphondylia resinosa is a gall midge in the family Cecidomyiidae that induces distinctive resinous galls on creosote bush (Larrea tridentata). The species was described by Gagné in 1990 and is one of approximately 15 Asphondylia species known to induce galls on creosote bush. Like other gall midges, the larva develops inside the plant tissue, with the gall providing both shelter and nutrition. The specific epithet 'resinosa' refers to the resinous character of the galls it produces.
Digrammia colorata
creosote moth
Digrammia colorata, commonly known as the creosote moth, is a species of geometrid moth in the family Geometridae. It is native to arid regions of western North America where its larvae feed on creosote bush (Larrea tridentata), a relationship reflected in its common name. The species has been documented in Middle America and North America according to distribution records. It is one of approximately 4,000 species in the genus Digrammia, which are generally small to medium-sized moths with cryptic coloration.
Perarthrus linsleyi
Perarthrus linsleyi is a species of longhorned beetle in the family Cerambycidae, described by Knull in 1942. The species is associated with creosote bush (Larrea tridentata) in arid and semi-arid environments. Adults feed on creosote bush flowers and mate on flowers and foliage. The species exhibits a scramble competition mating system characterized by male-wide ranging search behavior and absence of resource or mate defense.
