Moth proboscis morphology material properties raw data
<p>Insects have evolved unique structures that host a diversity of material and mechanical properties, and the mouthparts (proboscis) of butterflies and moths (Lepidoptera) are no exception. Here, we examined proboscis morphology and material properties from several previously unstudied moth lineages to determine if they relate to flower-visiting and non-flower-visiting feeding habits. Scanning electron microscopy and 3D imaging were used to study proboscis morphology and assess surface roughness patterns on the galeal surface, respectively. Confocal laser scanning microscopy was used to study patterns of cuticular autofluorescence, which was quantified with color analysis software. We found that moth proboscises display similar color and morphological patterns in relation to these feeding habits as those previously described for flower and non-flower-visiting butterflies. The distal region of proboscises of non-flower visitors is brush-like for augmented capillarity and exhibited blue autofluorescence, indicating the possible presence of resilin and increased flexibility. Flower visitors have smoother proboscises and show red autofluorescence, an indicator of high sclerotization, which is adaptive for floral tube entry. We propose the lepidopteran proboscis as a model structure for understanding how insects have evolved a suite of morphological and material adaptations to overcome the challenges of acquiring fluids from diverse sources.</p>
Proboscis curling in a pollinator causes extensive pollen movement and loss
<p>1. Precise pollen placement on floral visitors can improve pollen transfer, but in many plant species, pollen is deposited onto the flexible proboscises of long-tongued insects. These proboscises are curled and uncurled between floral visits, potentially causing pollen to be lost or displaced. Rates of pollen movement and loss resulting from proboscis curling, and hence the potential quality of long-tongued insects as pollinators, are unknown.</p> <p>2. Here we experimentally measure pollen loss and movement on the proboscises of <i>Manduca sexta </i>(Sphingidae)<i> </i>hawkmoths. We predicted that 1) proboscis curling causes pollen loss; 2) pollen that is not lost is displaced from its deposition site; and 3) repeated curls result in more displacement. We placed pollen from <i>Datura wrightii</i>, an important nectar plant for <i>M. sexta</i>,<i> </i>distal to the knee bend on <i>M. sexta </i>proboscises, and recorded the number and location of grains after proboscis curls.</p> <p>3. Consistent with our hypotheses, proboscis curling caused significant pollen loss. 1) A single curl resulted in the loss of almost 75% of the pollen from the placement site; after repeated curling, 98% of grains were lost from this site. 2) A single curl was also sufficient to displace pollen across all surfaces of the proboscis, but 3) further curling did not affect its distribution across surfaces.</p> <p>4. Together, these results suggest that precise pollen placement on the proboscises of hawkmoths would be unlikely to increase pollen transfer success. We discuss strategies by which flowering plants might mitigate the effects of pollen loss from visitors with flexible pollen-pickup structures.</p>
