Titanoeca americana
Titanoeca americana is a species of true spider in the family Titanoecidae, first described by Emerton in 1888. It is one of several species in the genus Titanoeca, which are small to medium-sized spiders characterized by their cribellate silk production. The species is known from North America, with records from the United States.
Tivyna
Tivyna is a genus of cribellate araneomorph spiders in the family Dictynidae, established by R. V. Chamberlin in 1948. The genus contains four species, all but one restricted to the United States. One species, T. spatula, has a broader Caribbean distribution including Mexico, Cuba, and the Bahamas. These spiders are characterized by the presence of a cribellum, a silk-producing organ used to create woolly, non-sticky capture silk.
Toxomerus parvulus
Black-backed Calligrapher
Toxomerus parvulus is a small hover fly in the family Syrphidae, commonly known as the Black-backed Calligrapher. The genus Toxomerus is exceptionally diverse in the Neotropics, with over 144 species, though many remain understudied. Larval feeding habits in this genus have historically been assumed to be predatory, but some species have been discovered to feed on pollen, indicating dietary diversity within the genus.
Trogomorpha
Trogomorpha is a genus of parasitoid wasps in the family Ichneumonidae. Species in this genus are poorly documented in public literature, with most information limited to taxonomic records. They are part of the diverse ichneumonid radiation, one of the largest families of Hymenoptera. The genus was established by William Harris Ashmead in 1900.
Welderella
Welderella is a genus of snout moths in the family Pyralidae, described by Blanchard in 1978. The genus is known from very few records, with only two observations documented on iNaturalist. As a higher-rank taxon with limited available data, most aspects of its biology remain uncharacterized.
Xanthorhoe packardata
Packard's Carpet
Xanthorhoe packardata, commonly known as Packard's Carpet, is a North American moth species in the family Geometridae. Described by James Halliday McDunnough in 1945, this species belongs to the diverse carpet moth genus Xanthorhoe. The species has been documented across prairie and boreal regions of Canada and the northern United States, with 265 observations recorded on iNaturalist. As with many Xanthorhoe species, detailed biological information remains limited in the scientific literature.
Xubida punctilineella
Xubida punctilineella is a crambid moth described by Barnes and McDunnough in 1913. The species is known from very few observations, with records limited to Florida in North America. Like other members of the genus Xubida, it is a small moth, but specific details about its biology remain poorly documented due to its rarity in collections and limited study.
