Intricate associations between floral morphology and pollinator foraging behaviour are common. In this context, the presence and form of floral nectaries can play a crucial role in driving floral evolution and diversity in flowering plants. However, the reconstruction of the ancestral state of nectary form is often hampered by a lack of anatomical studies and well-resolved phylogenetic trees. Here, we studied 39 differentially pollinated Pedicularis spp., a genus with pronounced interspecific variation in colour, shape and size of the corolla. Anatomical and scanning electron microscopy observations revealed two nectary forms [bulged (N = 27) or elongated (N = 5)] or the absence of nectaries (N = 7). In a phylogenetic context, our data suggest that: (1) the bulged nectary should be the ancestral state; (2) nectaries were independently lost in some beaked species; and (3) elongated nectaries evolved independently in some clades of beakless species. Phylogenetic path analysis showed that nectary presence is indirectly correlated with beak length/pollinator behaviour through an intermediate factor, nectar production. No significant correlation was found between nectary type and nectar production, beak length or pollinator behaviour. Some beaked species had nectary structures, although they did not produce nectar. The nectary in beaked species may be a vestigial structure retained during a recent rapid radiation of Pedicularis, especially in the HimalayaHengduan Mountains of south-western China.

“…The change of color needs different time in different species, generally requiring 2-5 days, but it may also extend to one month (Delph and Lively, 1989;Lamont, 1985;Nuttman and Willmer, 2003;Sun et al, 2005). The quick color change in B. sacra is linked to the anthocyanin accumulation which was shown to occur within 24 h in flowers of Cymbidium, developing into dark red within the following day (Woltering and Somhorst, 1990).…”

“…Indeed, this system benefits both pollinators, which obtain nourishment from pollen and nectar, and plant which receives an effective pollination, directing pollinators towards receptive flowers. Usually, the change of color occurs simultaneously to the loss of the stigma receptivity, marking by this way the span of time useful for pollination (Ida and Kudu, 2003;Lamont, 1985;Oberrath and Böhning-Gaese, 1999;Sun et al, 2005;Weiss, 1991).…”

“…The quantity of nectar in a flower fluctuates through time as it has been depleted by several ways including animal foraging (Corbet 2003). Many flowers change in colour with age, the colour of young flowers, particularly of yellow ones which are usually nectar-rich turns to red (Niesenbaum et al 1999;Ida & Kudo 2003) or from white to purple (Sun et al 2005) when nectar is no longer produced (Casper & La Pine 1984;Weiss 1991;Niesenbaum et al 1999). Evidence of preference for certain flower colours regarding foraging comes from a number studies.…”

What colour of flowers do Lepidoptera prefer for foraging?

Food plant preferences of some Lepidoptera species associated with particular colour of the flowers were investigated. Based on 1,329 field observations of 43 Lepidoptera and 66 plant species, Lepidoptera showed a high tendency (G-test, G adj = 698.6, df = 6, P < 0.001) to use the yellow (29%) and pink (28%) coloured flowers for foraging. Compared to the other colours it was evident that plants with red flowers (2%) were not preferred. Moreover, the plants with red (H = 0.435) and yellow-white (H = 0.543) flowers were not visited by diverse Lepidoptera species. Although yellow and pink flowers were most frequently visited, the highest degrees of the Lepidoptera diversity values were associated with the plants having blue (H = 0.647) and purple (H = 0.634) flowers. Species of Nymphalidae were most numerous (14 spp.) in the study area and the members of this family were observed 430 times on 39 different plant species, but never on plants with red flowers. Pieris rapae was the most abundant species that occurred 136 times on a total of 21 different plant species of which eight had yellow flowers. But, this species has never been seen while feeding on red flowers.
