Calycomyza avira
Calycomyza avira is a species of leaf-mining fly in the family Agromyzidae, described from North America in 2018. Like other members of its genus, it likely produces serpentine or blotch mines in living leaf tissue. The species was established based on morphological distinctions from congeners and associated host plant records. It represents part of a diverse radiation of Calycomyza species specialized on Asteraceae hosts.
Ophraella bilineata
Skeletonizing leaf beetle
Ophraella bilineata is a species of skeletonizing leaf beetle in the family Chrysomelidae. The species is characterized by its distinctive striped elytra and is found across North America. As a member of the Galerucinae subfamily, it exhibits the typical leaf beetle morphology with compact body form and herbivorous feeding habits.
Rekoa palegon
gold-bordered hairstreak

It ranges from Argentina through Mexico and the West Indies, with rare occurrences in southern Texas. Adults have a wingspan of 23–28 mm and are active from May through December in Mexico, with a single annual generation. The species has been documented feeding on nectar from Senecio and Eupatorium flowers.
Zygogramma
Zygogramma is a large genus of leaf beetles in the subfamily Chrysomelinae, comprising approximately 100 species with 13 species occurring north of Mexico. The genus is characterized by its association with plants in the family Asteraceae, particularly ragweeds (Ambrosia) and related genera. Several species, especially Z. bicolorata, have been extensively studied and deployed as biological control agents against invasive weeds. The genus is distinguished from related genera such as Calligrapha by fused tarsal claws.
