Lepidoptera
- At first glance, the monarch butterfly seems built for beauty, not endurance. Its paper-thin wings look like they could tear in a strong breeze, and its delicate body appears better suited for floating between flowers than crossing continents. Yet these seemingly fragile creatures pull off one of nature's most incredible feats: a 3,000-mile migration. Just like geese, caribou, and senior citizens, they undertake this migration to avoid the harsh winters of the north.

Perilitini
Perilitini is a small tribe of braconid wasps in the subfamily Microgastrinae. Members are koinobiont endoparasitoids of lepidopteran larvae, primarily associated with hosts in the family Noctuidae (owlet moths). The tribe is characterized by reduced wing venation and a compact body form. Taxonomic boundaries within Perilitini have been historically unstable, with some genera transferred to or from related tribes based on molecular phylogenetic studies.
Perimede ricina
Perimede ricina is a small moth described by Ronald W. Hodges in 1962. The species is currently classified in the family Momphidae, though it was historically placed in Cosmopterigidae. It occurs in eastern and central North America, with records spanning from Louisiana to Massachusetts. Adults are active primarily during spring through fall, with some late-season activity in November.
Periploca
Periploca is a genus of small moths in the family Cosmopterigidae. The genus was established by Braun in 1919. Larvae of at least one species, Periploca ceanothiella, have been documented as hosts for the ichneumonid parasitoid wasp Calliephialtes grapholithae.

The species is known from only a handful of observations, with limited biological information available. Like other members of Petrophila, it is likely associated with aquatic or riparian habitats, though this has not been directly documented for this species.
Pexicopiini
Pexicopiini is a tribe of small moths within the subfamily Anomologinae of the family Gelechiidae, established by Hodges in 1986. The tribe is characterized by specific morphological features of the male genitalia, particularly musculature patterns that distinguish constituent genera. Recent taxonomic work has clarified relationships within the tribe, including the establishment of new genera based on functional morphology of genital structures. The tribe includes genera distributed primarily in the Palearctic region.
Phaegopterina
Phaegopterina is a subtribe of tiger moths within the tribe Arctiini (subfamily Arctiinae, family Erebidae). First described by William Forsell Kirby in 1892, it was formerly classified as the tribe Phaegopterini of family Arctiidae. The subtribe contains approximately 750 species recorded in Brazil alone, with 469 species documented in the Amazon region and 254 in the Cerrado.

The genus has undergone taxonomic revision, previously placed in the subfamily Phytometrinae within Erebidae or in Calpinae within Noctuidae. It now resides in Boletobiinae, tribe Phytometrini. The genus contains approximately 40 described species distributed across multiple continents, with notable species including Phytometra viridaria (small purple-barred) and Phytometra rhodarialis (pink-bordered yellow moth).
Pieridae
Whites, Yellows, Sulphurs, Orangetips
Pieridae is a large family of butterflies containing approximately 76 genera and 1,100 species, characterized by white, yellow, or orange coloration with black markings. The family was established by William Swainson in 1820. The name "butterfly" is believed to derive from the brimstone (Gonepteryx rhamni), a member of this family historically called the "butter-coloured fly." The family is divided into four subfamilies: Dismorphiinae, Pierinae, Coliadinae, and Pseudopontiinae. Many species are economically significant as agricultural pests, particularly those feeding on brassicas.

The "nr" designation indicates morphological or genetic similarity to P. murtfeldtella, a described North American species, but not confirmed conspecificity. Members of this genus are characterized by their minute size and the larval habit of constructing portable cases from silk and plant material. This taxon is known from North American records, particularly in association with oak and other woody plants.
