Journal ArticleDOI
Lamp-lit bridges as dual light-traps for the night-swarming mayfly, Ephoron virgo: interaction of polarized and unpolarized light pollution.
Dénes Száz,Gábor Horváth,András Barta,Bruce A. Robertson,Alexandra Farkas,Ádám Egri,Nikolett Tarjanyi,Gergely Racz,György Kriska +8 more
TL;DR: It is confirmed that Ephoron virgo is independently attracted to both unpolarized and polarized light sources, that both types of photopollution are being produced at the bridge, and that spatial patterns of swarming and oviposition are consistent with evolved behaviors being triggered maladaptively by these two types of light pollution.

Stripes disrupt odour attractiveness to biting horseflies: Battle between ammonia, CO2, and colour pattern for dominance in the sensory systems of host-seeking tabanids
Miklós Blahó,Ádám Egri,Dénes Száz,Gyoergy Kriska,Gyoergy Kriska,Susanne Åkesson,Gábor Horváth +6 more
TL;DR: It is shown here that striped targets are significantly less attractive to host-seeking female tabanids than homogeneous white or black targets, even when they emit tabanid-luring CO2 and ammonia, which demonstrates the visual protection of striped coat patterns against attacks from blood-sucking dipterans, such as horseflies, known to transmit lethal diseases to ungulates.
Journal ArticleDOI
Polarization transition between sunlit and moonlit skies with possible implications for animal orientation and Viking navigation: anomalous celestial twilight polarization at partial moon.
András Barta,Alexandra Farkas,Dénes Száz,Ádám Egri,Pál Barta,József Kovács,B. Csák,I. Jankovics,Gyula M. Szabó,Gábor Horváth +9 more
TL;DR: It is found that at partial moon and at a medium latitude during this transition there is a relatively short period when (i) the maximum of p of skylight decreases, and (ii) from the celestial α pattern neither the solar-antisolar nor the lunar-antilunar meridian can be unambiguously determined.
Journal ArticleDOI
Introducing the dark sky unit for multi-spectral measurement of the night sky quality with commercial digital cameras
Zoltán Kolláth,Andrew Cool,Andreas Jechow,Andreas Jechow,Kornél Kolláth,Dénes Száz,Kai Pong Tong +6 more
TL;DR: This paper shows how to make better use of the multi-spectral capabilities of commercial digital cameras and shows their application for airglow analysis, and recommends a novel sky quality metric the “Dark Sky Unit”, based on an easily usable and SI traceable unit.
Journal ArticleDOI
A new tabanid trap applying a modified concept of the old flypaper: linearly polarising sticky black surfaces as an effective tool to catch polarotactic horseflies.
Ádám Egri,Miklós Blahó,Dénes Száz,András Barta,György Kriska,György Kriska,Györgyi Antoni,Gábor Horváth +7 more
TL;DR: A new horsefly trap called "horseflypaper" is constructed based on earlier findings on the positive polarotaxis (attraction to linearly polarised light) in tabanid flies and modifying the concept of the old flypaper, which catches water-seeking male and female tabanids.
