Chrysomela
leaf beetles
Chrysomela is a genus of leaf beetles in the family Chrysomelidae, containing approximately 40 species distributed across most continents except Australia. The genus is notable for its chemical defense mechanisms, with larvae producing volatile compounds derived from host plant chemistry. Several species are economically significant, including the cottonwood leaf beetle (C. scripta) in North America. Research on Chrysomela species has contributed to understanding plant-herbivore interactions, local adaptation, and chemical ecology.
Cryptolestes pusillus
Flat Grain Beetle, Red Flat Grain Beetle
Cryptolestes pusillus, commonly known as the flat grain beetle or red flat grain beetle, is a species of lined flat bark beetle in the family Laemophloeidae. Native to Europe, it has become a cosmopolitan pest of stored grain products. The species is frequently studied as a model organism for stored product pest management and biological control research, serving as prey for predatory bugs and host for parasitoid wasps.
