Photinus indictus
Silent Firefly
Photinus indictus, commonly known as the silent firefly, is a diurnal firefly species in the beetle family Lampyridae. Adults are active during daylight hours and lack the bioluminescent lanterns characteristic of most fireflies, earning both its common name and specific epithet (Latin for "unspoken"). The species is found in eastern North America, particularly the Great Lakes region. Adults communicate through airborne pheromones rather than light signals.
Trichosirocalus
rosette weevils, crown weevils
A genus of small true weevils native to the Palearctic region. Several species have been widely introduced to North America, Australia, and New Zealand as biological control agents for invasive thistles. The genus was historically treated as containing a single species, T. horridus, but integrative taxonomic studies using molecular and morphological data have revealed multiple distinct species with different host associations.
