The visual systems of Calliphoridae species (blow flies), Parus caeruleus Eurasian blue tit, Zootoca vivipara lizard and Vespula vulgaris wasp are all highly sensitive to Lucilia richardsi’s visual appearance, as shown here in terms of quantum catches. Due to its reflectance peak at 537 nm, L. richardsi’s colour gives rise to a high absorption by the LWS photoreceptors of the Eurasian blue tit, the blow fly and the common wasp as well as by the MWS photoreceptors of the common lizard.
