Kāpēc naktstauriņu pievilina gaisma?
17, 2007, 17:06Dāvis
:-:

    Visticamāk tādēļ, ka tauriņi gaismu saujauc ar lielu ziedu. Naktī ziedošie augi ir gaišās krāsās. Tas, ka gaisma ir par daudz gaiša, laikam tauriņus nemulsina :( Varbūt tāpēc, ka šie redz ultravioleto gaismu un ar tās palīdzību meklē ziedus? Lampu pievilcība kukaiņu acīs ir atšķirīga dažādām lampām. Ja parastai lampai pieliek priekšā ultravioleto filtru, kukaiņi vairs uz šo lampu tā nemaz netraucoties.
