Achromatic Cues Are Important for Flower Visibility to Hawkmoths and Other Insects
Frontiers in Ecology and Evolution, 2022 Studies on animal colour vision typically focus on the chromatic aspect of colour, which is related to the spectral distribution, and disregard the achromatic aspect, which is related to the intensity (“brightness”) of a stimulus.

Hawkmoths produce anti-bat ultrasound [PDF]
Biology Letters, 2013 Bats and moths have been engaged in aerial warfare for nearly 65 Myr. This arms race has produced a suite of counter-adaptations in moths, including bat-detecting ears. One set of defensive strategies involves the active production of sound; tiger moths' ultrasonic replies to bat attack have been shown to startle bats, warn the predators of bad taste ...

Hawkmoth flight in the unsteady wakes of flowers [PDF]
Journal of Experimental Biology, 2018 Abstract Flying animals maneuver and hover through environments where wind gusts and flower wakes produce unsteady flow. Although both flight maneuvers and aerodynamic mechanisms have been studied independently, little is known about how these interact in an environment where flow is already unsteady.

Frontiers in Cellular Neuroscience, 2018 For the hawkmoth Manduca sexta accumulating evidence suggests that pheromone transduction acts via a metabotropic signal transduction cascade, with G-protein-dependent phospholipase C (PLC) activations generating diacylglycerol (DAG) and inositol ...

Flower tracking in hawkmoths: behavior and energetics [PDF]
Journal of Experimental Biology, 2007 SUMMARY As hovering feeders, hawkmoths cope with flower motions by tracking those motions to maintain contact with the nectary. This study examined the tracking, feeding and energetic performance of Manduca sexta feeding from flowers moving at varied frequencies and in different directions.

Direct lateral maneuvers in hawkmoths
Biology Open, 2016 ABSTRACT We used videography to investigate direct lateral maneuvers, i.e. ‘sideslips’, of the hawkmoth Manduca sexta. M. sexta sideslip by rolling their entire body and wings to reorient their net force vector. During sideslip they increase net aerodynamic force by flapping with greater amplitude, (in both wing elevation and sweep ...

Colour Vision in Diurnal and Nocturnal Hawkmoths [PDF]
Integrative and Comparative Biology, 2003 Diurnal and nocturnal hawkmoths (Sphingidae, Lepidoptera) have three spectral types of receptor sensitive to ultraviolet, blue and green light. As avid flower visitors and pollinators, they use olfactory and visual cues to find and recognise flowers.

Dynamics of pine hawkmoth (Hyloicus pinastri L.): Search for stationary dynamical regime [PDF]
Computational Ecology and Software, 2013 In current publication possible population dynamics regimes are analyzed using pre-model statistical method. Method was applied to well-known pine hawkmoth (Hyloicus pinastri L.) time series (Schwerdtfeger, 1944, 1968).

A new Ypsilopus (Orchidaceae, Angraecinae) from Zimbabwe and notes on the parallel evolution of extreme column exsertion in African angraecoids [PDF]
Plant Ecology and Evolution, 2023 Background and aims – A preliminary review of hawkmoth-pollinated angraecoids from Africa unveiled a remarkable case of parallel evolution of extreme column exsertion between the two species formerly classified in in the defunct genus Barombia.
