Learning of Multi-Modal Stimuli in Hawkmoths
PLoS ONE, 2013 The hawkmoth, Manduca sexta, uses both colour and odour to find flowers when foraging for nectar. In the present study we investigated how vision and olfaction interact during learning. Manduca sexta were equally attracted to a scented blue coloured feeding target (multimodal stimulus) as to one that does not carry any scent (unimodal stimulus; visual)

A linear systems analysis of the yaw dynamics of a dynamically scaled insect model [PDF]
, 2010 Recent studies suggest that fruit flies use subtle changes to their wing motion to actively generate forces during aerial maneuvers. In addition, it has been estimated that the passive rotational damping caused by the flapping wings of an insect is ...

Variation and evolution of herkogamy in Exochaenium (Gentianaceae): implications for the evolution of distyly [PDF]
, 2017 Backgrounds and Aims The spatial separation of stigmas and anthers (herkogamy) in flowering plants functions to reduce self-pollination and avoid interference between pollen dispersal and receipt.

Frontiers in Ecology and Evolution, 2018 Most pollinators visit flowers in the search of nectar rewards. However, as the floral nectar can often not be directly detected by pollinators, many flower visitors use secondary metabolites such as odor- or taste-proxies to anticipate nectar quantity ...

Kibale ARU hawkmoth ID guide 2018
, 2018 This is an identification guide to hawkmoths (Sphingidae) of Kibale National Park in Uganda. It is is the form of an interactive pdf, allowing it to be used on a computer, phone or tablet. It has been produced to help students and staff on the annual Anglia Ruskin field trip to KIbale identify the hawkmoths we see.

The vortex wake of a ‘hovering’ model hawkmoth
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1997 Visualization experiments with Manduca sexta have revealed the presence of a leading–edge vortex and a highly three–dimensional flow pattern. To further investigate this important discovery, a scaled–up robotic insect was built (the ‘flapper’) which could mimic the complex movements of the wings of a hovering ...
