Catocala nebulosa
Clouded Underwing
Catocala nebulosa is a large underwing moth native to eastern and central North America. Adults are nocturnal and active from July to September, with a single generation per year. The species exhibits the characteristic underwing defense: cryptic forewings conceal brightly patterned hindwings that are flashed to startle predators. Larvae feed on bitternut hickory and black walnut.
Chrysina woodi
Wood's jewel scarab
Chrysina woodi is a metallic green scarab beetle in the family Scarabaeidae, commonly known as Wood's jewel scarab. Adults measure 25–35 mm in length and are distinguished by their bright green coloration with green legs and blue tarsi. The species is native to the Chihuahuan Desert region, occurring in Chihuahua, Mexico, and extending into New Mexico and Texas in the United States. Adults have been documented feeding primarily on Texas black walnut (Juglans microcarpa). The species name was first published in 1884 as 'woodi' and takes precedence over the subsequent 'woodii' spelling of 1885 under ICZN Article 50.2.
