Mitrastemon yamamotoi is completely embedded within the tissues of its hosts, except during the reproductive stage, when aboveground parts emerge from host tissues. Its highly modified appearance has attracted attention of many botanists, but very little is known about the reproductive system. Floral visitors to M. yamamotoi were observed in southern Japan. Pollination experiments were conducted to determine the plant's self-compatibility and pollen limitation, as well as the contribution of diurnal and nocturnal visitors to fruit set and outcrossing. Mitrastemon yamamotoi is mainly pollinated by social wasps, but previously unnoticed pollinators (i.e. crickets and cockroaches) are also important, based on visitation frequency and pollen loads. Results of the pollination experiments suggest that nocturnal visitors, such as crickets and cockroaches, contribute to geitonogamous pollination, whereas diurnal visitors, such as social wasps, facilitate outcrossing. The unexpected pollinator assemblage of M. yamamotoi might be influenced by multiple factors, including the highly modified flowers that are produced close to the ground in dark understorey environments, the species' winter-flowering habit and the location of the study site (i.e. near the northern limit of the species' range). Considering that M. yamamotoi occurs widely in subtropical and tropical forests in Asia, additional studies are needed to assess pollinator assemblages of M. yamamotoi at other locations.

“…This may suggest that even though P. brevis visits flowers frequently, each individual may not be that efficient in damaging the reproductive parts and controlling weeds. Tan and Tan (2018a) also postulated that such behavior can help with pollination, but there is hitherto no direct evidence on how P. brevis can improve reproductive success of non-native weeds. Since P. brevis feeds mainly on nonnative species, it is also unlikely that P. brevis has adapted to pollinating them and that any transfer of pollen is probably an artefact of its opportunistic feeding strategy.…”

“…Since P. brevis feeds mainly on nonnative species, it is also unlikely that P. brevis has adapted to pollinating them and that any transfer of pollen is probably an artefact of its opportunistic feeding strategy. Therefore, in addition to the insectary experiment (Tan and Tan 2018a) and our observational study, controlled nursery or greenhouse experiments will also be needed to investigate more explicitly and quantify the feeding and pollination efficiencies of P. brevis to better understand their roles as flower visitors.…”

“…1) is a tropical floriphilic katydid from Southeast Asia which has been observed to visit and feed on the flowers of many host-plant species (Tan et al 2017a). Although Tan and Tan (2018a) recently also observed that the gentle foraging behavior can help with pollination in an insectary setting, we are unaware of how abundant these flowervisiting katydids are in their natural environment, how frequently they visit flowers, and why. Without these data, it is not possible to assess the importance of these flower-visiting katydids in flowering communities and their pollinating efficiency.…”

Distribution of consumers in a patch of vegetation can be predicted by resource availability and explained by the resource-concentration and optimal-foraging hypotheses. These hypotheses have not been explored for flower-visiting Orthoptera because they are deemed less economically or ecologically important. Some flower-visiting orthopterans can provide pollination services, which warrants more attention. We studied a Singaporean, floriphilic katydid, Phaneropterabrevis, to investigate the following questions: 1) how frequently does P.brevis visit flowers compared to other flower visitors and 2) what factors predict the abundance of P.brevis? We collected abundance data for P.brevis and other flower-visiting arthropods and quantified seven environmental parameters, including flower abundance and host-plant species richness. We found that P.brevis frequents flowers significantly more often than some common and expected flower visitors such as hoverflies. In line with the prediction of the resource-concentration hypothesis, the abundance of P.brevis was positively correlated with a higher flower abundance. Owing to the limited information on unexpected wild flower visitors and pollinators, especially from the understudied tropics of Southeast Asia, we propose that P.brevis can be a model organism for future studies to answer fundamental questions on flower visitation.

“…These in turn imply that florivores can have direct and indirect consequences on floral adaptations and community dynamics of flowers and flower‐visitors (Frame, ; Krupnick, Weis, & Campbell, ; McCall & Irwin, ). Moreover, florivores can also potentially contribute to pollination although so far are poorly understood (e.g., Tan & Tan, ). Nonetheless, the study of florivores and florivory is still generally neglected and has received less attention compared to leaf herbivory and pollination (McCall & Irwin, ).…”

Behaviour, including personality, informs us about the response of animals towards their changing environment. Despite the widespread occurrence of florivorous insects and the important but often underrated ecological roles that they play, the study of florivore behaviour is neglected relative to that of pollinators and other herbivores. Specifically, we do not know how different personality types can develop among florivores and enable them to persist in habitats with an ephemeral and dynamic availability of food resources. To address this knowledge gap, we investigated the following questions: whether the (a) inter‐individual differences of exploration and boldness are consistent; (b) inter‐population differences of exploration and boldness are consistent; (c) exploration and boldness are correlated. We collected individuals of the polyphagous floriphilic katydid, Phaneroptera brevis from four populations from wasteland sites in Singapore and performed a personality assay conducted in an insectary to investigate the exploratory and boldness levels of the individuals and populations. The major novel finding was that the floriphilic P. brevis katydids exhibit population‐level personality types for boldness, but not for exploration. Some katydid individuals were consistently more exploratory and bolder than other individuals. However, contrary to our predictions, we did not find any evidence of behavioural syndromes in the katydid individuals, as the boldness level for individuals was not significantly correlated with exploration for individuals. This suggests that an individual which is more exploratory may not be equally keen to take risks and consume novel food that it encounters. Our findings also suggest that boldness and exploration are linked to ecologically important behaviours, but more studies are needed to better understand population‐level personality and how and why natural selection may favour the evolution of personality in certain populations.
