Guttipelopia
Guttipelopia is a genus of non-biting midges in the subfamily Tanypodinae, family Chironomidae. The genus is distinguished by distinctive wing pigmentation patterns featuring darkened areas (guttae) on the wing membrane. Taxonomic review has clarified species boundaries, confirming the conspecificity of Nearctic G. multipunctata and Palaearctic G. guttipennis, with G. currani synonymized under the latter. The genus contains three recognized species: G. guttipennis, G. currani, and G. rosenbergi.
Hetaerina titia
smoky rubyspot
Hetaerina titia, the smoky rubyspot, is a broad-winged damselfly in the family Calopterygidae. It is one of the most commonly encountered odonates along streams and rivers from Panama to southern Canada, representing the largest latitudinal range of any species in the genus Hetaerina. The species exhibits highly variable wing melanin pigmentation, both seasonally and geographically, and has become a model system for studying sexual selection and interspecific behavioral interference. Its IUCN conservation status is Least Concern with a stable population.
