Silene latifolia

Hadena moths use Silene flowers (Caryophyllaceae) as both nectar sources and as host plants for depositing larvae. The floral scent of Silene latifolia is characterized by the presence of several fatty acid derivatives, benzenoids, and monoterpenoids, while the most abundant compounds are the lilac aldehyde isomers ((2 S, 2 S, 5 S), (2R, 2 S, 5 V), (2S, 2 R, 5 S), and (2R, 2 R, 5 S )) (23), veratrole, and benzyl acetate.93 However, several chemotypes of these dominant components are found in S. latifolia, suggesting variability in attracting pollinators. Wind tunnel experiments have revealed that Hadena bicruris is strongly attracted by lilac aldehyde isomers although the moths respond electrophysiologically to all eight stereoisomers of lilac aldehyde, only four are present in the floral scent.94...
