Continuous monitoring of aerial density and circadian rhythms of flying insects in a semi-urban environment.

Although small in size, insects are a quintessential part of terrestrial ecosystems due to their large number and diversity. While captured insects can be thoroughly studied in laboratory conditions, their population dynamics and abundance in the wild remain largely unknown due to the lack of accura...
