Ataxia hubbardi
Ataxia hubbardi is a longhorned beetle (Cerambycidae) described by Warren Samuel Fisher in 1924. The species is distributed across the United States and Mexico. Adults are active in fall and have been observed on flower stalks of host plants. A distinctive population associated with prairie dock (Silphium terebinthinaceum) in Missouri dolomite glades exhibits smaller, darker, and narrower body proportions compared to typical individuals.
Dicerca pugionata
witch-hazel borer, ninebark borer
A striking jewel beetle in the family Buprestidae, measuring 11–14 mm in length. Unlike most Dicerca species that breed in dead wood, D. pugionata larvae mine living stems of woody shrubs. The species occurs sporadically across eastern North America but reaches locally abundant populations in Missouri glades where host plants grow under stressed conditions.
