“…Color-opponent responses have not yet been demonstrated electrophysiologically in flies, although there is evidence for them in honey bees (Hertel, 1980). However, there is good behavioral evidence for color vision in the flies Lucilia and Drosophila (Fukushi, 1990;Herná ndez de Salomon and Spatz, 1983;Menne and Spatz, 1977;Tang and Guo, 2001).…”

Anatomical methods have identified conserved neuronal morphologies and synaptic relationships among small-field retinotopic neurons in insect optic lobes. These conserved cell shapes occur across many species of dipteran insects and are also shared by Lepidoptera and Hymenoptera. The suggestion that such conserved neurons should participate in motion computing circuits finds support from intracellular recordings as well as older studies that used radioactive deoxyglucose labeling to reveal strata with motion-specific activity in an achromatic neuropil called the lobula plate. While intracellular recordings provide detailed information about the motion-sensitive or motion-selective responses of identified neurons, a full understanding of how arrangements of identified neurons compute and integrate information about visual motion will come from a multidisciplinary approach that includes morphological circuit analysis, the use of genetic mutants that exhibit specific deficits in motion processing, and biomimetic models. The latter must be based on the organization and connections of real neurons, yet provide output properties similar to those of more traditional theoretical models based on behavioral observations that date from the 1950s.

“…Both innate color preferences and an ability to learn to associate color with the presence of reward have been demonstrated in a broad range of pollinating insects, including hymenopterans (von Frisch, 1971;Menzel and Erber, 1978;Menzel, 1985;Giurfa et al, 1995Giurfa et al, ), dipterans (llse, 1949Menne and Spatz, 1977;Fukushi, 1985Fukushi, , 1990Pickens, 1990;Troje, 1993), and lepidopterans (Swihart and Swihart, 1970;Swihart, 1971;Scherer and Kolb, 1987a,b;Goulson and Cory, 1993;Weiss, 1995b;Kelber, 1996;Kelber and Pfaff, 1997, this issue).…”

Flowers in a wide range of angiosperm taxa (at least 456 species in 253 genera and 78 families) undergo dramatic ontogenetic color changes that serve as signals to their insect pollinators. The changes affect a diversity of floral parts, involve all three major classes of floral pigments, and produce a broad spectrum of initial and final colors. A diverse array of insect pollinators (in at least 21 families in four orders) recognize and respond to floral color phases, visiting pre-change flowers preferentially, relative to their contribution to the total floral display. A variety of hypotheses have been proposed to explain the functional significance of floral retention and color change. Experimental results demonstrate that in some cases retention of older flowers on the plant results in increased visitation by pollinators from a distance, while at close range, color change directs visitors towards the rewarding and sexually viable younger flowers. The interaction does not require a long coevolutionary association: both native and exotic insect species discriminate between floral color phases on native and introduced plant species. This flexibility is based at least in part on learning by the insect, although innate color preferences may also be important.

“…Fly colour vision has been well studied at a genetic level (Mazzoni et al 2008;Yamaguchi et al 2010), and there is solid evidence of multiple types of spectrally different photoreceptors (Lunau 2014), as well as a demonstrated capacity in both the blowfly (Lucilia cuprina) and the dronefly (Eristalis tenax) to discriminate colour information (Ilse 1949;Fukushi 1990;Lunau 2014). Recent work has also reported evidence of opponent-type processing in Drosophila (Gao et al 2008).…”

Floral colours in a world without birds and bees: the plants of Macquarie Island

et al. 2016

We studied biotically pollinated angiosperms on Macquarie Island, a remote site in the Southern Ocean with a predominately or exclusively dipteran pollinator fauna, in an effort to understand how flower colour affects community assembly. We compared a distinctive group of cream-green Macquarie Island flowers to the flora of likely source pools of immigrants and to a continental flora from a high latitude in the northern hemisphere. We used both dipteran and hymenopteran colour models and phylogenetically informed analyses to explore the chromatic component of community assembly. The species with cream-green flowers are very restricted in colour space models of both fly vision and bee vision and represent a distinct group that plays a very minor role in other communities. It is unlikely that such a community could form through random immigration from continental source pools. Our findings suggest that fly pollination has imposed a strong ecological filter on Macquarie Island, favouring floral colours that are rare in continental floras. This is one of the strongest demonstrations that plant-pollinator interactions play an important role in plant community assembly. Future work exploring colour choices by dipteran flower visitors would be valuable.
