Effect of weather conditions on light-trap catches of Trichoptera in Hungary (Central Europe)

The study deals with the effect of weather conditions on the light trap catch of 2 caddisflies (Trichoptera) species: Hydropsyche bulgaromanorum and Setodes punctatus. We found that the light trap catch of both species increased when the daily maximum temperature, minimum and average values of temperature was higher. The results can be written down with second- or third-degree polynomials. The fluctuation in temperature had no clear influence on the catch. The hydrothermal quotient has a strong influence on the catch of both species. Precipitation has no significant influence on the catch of the tested species.
