Gymnocarena
fruit flies
Gymnocarena is a genus of true fruit flies (family Tephritidae) comprising 19 described species. Most species are native to North America, with one species (G. monzoni) recorded from Guatemala. Larvae develop within the heads of plants in the sunflower family (Asteraceae), feeding on developing seeds and acting as seed predators. Several species are associated with cultivated sunflower (Helianthus annuus) and can be agricultural pests. Adults are characterized by patterned wings typical of tephritid fruit flies.
Mordellistena
tumbling flower beetles
A large genus of tumbling flower beetles comprising over 450 described species distributed worldwide. Adults are commonly found on flowers where they feed on pollen and nectar. Larvae develop within stems of herbaceous plants or in decaying wood, with some species exhibiting specialized host associations including agricultural pests of sunflower. The genus has been subject to extensive taxonomic revision due to morphological similarity among species and the importance of male genitalia for identification.
