Myochrous Explained

Myochrous is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North, Central and South America. There are over 50 described species in Myochrous.^{[1] [2] [3] [4]} The generic name is a combination of the Ancient Greek words (mouse) and (color).^[4]

The southern corn leaf beetle (Myochrous denticollis) is a crop pest, and has been reported to damage corn in Illinois.^[5] Additionally, the species Myochrous melancholicus has been reported to damage banana fruit.^[6]

According to BugGuide and ITIS, the genus is now placed in the tribe Eumolpini instead of Adoxini.^{[1] [2]}
