Dahake et al. (2018). The roles of vision and antennal mechanoreception in hawkmoth flight control. eLife.
- The page saysGalium is the caterpillars' native host plant
- The source says
Eggs were collected and the caterpillars raised on their native host plant Gallium sp.
Note: stats.diet; the paper spells the genus 'Gallium'; Galium is the plant genus - The page saysHovers in front of flowers, and the sensors in its antennae help it control rapid turns
- The source says
antennal mechanosensors play a key role in the control of hovering flight, specifically in the control of fast flight manoeuvres (rapid turns)
Note: stats.superpower - The page saysThe hummingbird hawk-moth feeds from flowers while hovering in front of them.
- The source says
M. stellatarum feed from flowers while hovering in front of them
- The page saysSix moths weighed in a flight-control study averaged 252 milligrams, about a quarter of a gram.
- The source says
we measured these quantities in six freshly sacrificed animals (three male, three female). The resulting average head:antenna ratio was 3.38:1 ± 0.68 standard deviation, with a weight of 10.5 ± 1.4 mg for the head and 3.1 ± 0.31 mg for the two antennae. The animals weighed an average of 252 ± 66 mg.
Note: 252 mg = 0.252 g - The page saysIn a flight-cage test, moths with the flagella removed from their antennae (the long outer part) jittered more around an artificial flower than moths with intact antennae.
- The source says
it was notable that flagella ablated moths jittered around their target position with larger amplitudes than moths of the other two antennal conditions
Note: other two conditions = control (intact) and re-attached; flight cage and artificial flower from the methods: we trained hawkmoths ( Macroglossum stellatarum ) in a flight cage to approach and hover in front of an artificial flower - The page saysThe authors report that antennal mechanosensors, which feel movement, play a key role in controlling hovering flight, especially fast manoeuvres such as rapid turns.
- The source says
antennal mechanosensors play a key role in the control of hovering flight, specifically in the control of fast flight manoeuvres (rapid turns)

Warrant, Bartsch & Günther 1999
Warrant, Bartsch & Günther (1999). Physiological optics in the hummingbird hawkmoth: a compound eye without ommatidia. Journal of Experimental Biology.
- The page saysA day-flying moth that hangs in front of flowers while a special patch of its eye fixes on the flower's entrance.
- The source says
It is this eye region that M. stellatarum uses to fixate flower entrances during hovering and feeding.
Note: tagline; the day-flying part is the 'day-active' of the same abstract (The fast-flying day-active hawkmoth Macroglossum stellatarum) - The page saysThe moth's eye has a frontal acute zone, a patch with larger facets and more densely packed light-sensing cells than the rest of the eye.
- The source says
By having larger facets, a wider aperture and denser rhabdom packing, the frontal acute zone of M. stellatarum provides the eye with its sharpest and brightest image
Note: rhabdoms are the light-sensing structures of the photoreceptors; 'than the rest of the eye' is the paper's gradient framing (maximal at the frontal acute zone: The size of the facets and the area of the superposition aperture are both maximal at the frontal retinal acute zone) - The page saysThat patch gives the sharpest and brightest image, and the moth uses it to fixate flower entrances during hovering and feeding.
- The source says
the frontal acute zone of M. stellatarum provides the eye with its sharpest and brightest image and samples the image with the densest photoreceptor matrix. It is this eye region that M. stellatarum uses to fixate flower entrances during hovering and feeding.
- The page saysIn the front of the eye there are up to four rhabdoms, the light-sensing structures, behind each facet, so the moth does not have ommatidia, the usual units of an insect eye, in the accepted sense.
- The source says
In fact, this eye has many more rhabdoms than facets, with up to four rhabdoms per facet in the frontal eye, a situation which means that M. stellatarum does not possess ommatidia in the accepted sense.
Note: 'the usual units of an insect eye' glosses ommatidia; the paper's title calls it 'a compound eye without ommatidia'

Telles et al. (2014). Out of the blue: the spectral sensitivity of hummingbird hawkmoths. Journal of Comparative Physiology A.
- The page saysElectrical recordings found light receptors for ultraviolet, blue and green, most sensitive at 349, 440 and 521 nanometres.
- The source says
Using behavioural tests and electroretinograms (ERGs), we studied the spectral sensitivity of M. stellatarum. By measuring ERGs in the dark-adapted eye and after adaptation to green light, we determined that M. stellatarum has ultraviolet (UV), blue and green receptors maximally sensitive at 349, 440 and 521 nm

- The source says
is known to feed from a variety of flower species of almost all colours, forms and sizes
- The page saysNewly emerged moths tested with artificial flowers had a strong preference for light of 440 nanometres, a weaker one for 540, and favoured disks about 32 millimetres across.
- The source says
The moths were found to have a strong preference for 440 nm and a weaker preference for 540 nm.
- The page saysfavoured disks about 32 millimetres across
- The source says
Disks of approximately 32 mm in diameter are preferred to smaller and larger ones
- The page saysSize mattered more to them than colour, and colour more than pattern.
- The source says
Tests using combinations of two parameters reveal that size is more important than colour and that colour is more important than pattern.
- The page saysBlue, by instinct.
- The source says
The moths were found to have a strong preference for 440 nm
Note: 440 nm is the blue receptor's peak in Telles et al. 2014; 'by instinct' = the innate preferences of newly eclosed imagines tested in this study

- The page saysIt flies by day
- The source says
the diurnal species, M. stellatarum
- The page saysA nocturnal lifestyle is ancestral for the hawk-moth family, and this species evolved from moths that flew at night.
- The source says
Since a nocturnal lifestyle is ancestral for sphingids, the diurnal species, M. stellatarum, has evolved from nocturnal moths that primarily used olfaction.
Note: sphingids = hawk-moth family (the paper names Sphingidae) - The page saysIn wind-tunnel tests, the day-flying hummingbird hawk-moth followed a visual cue, while a night-flying relative, the elephant hawk-moth, followed an odour.
- The source says
We tested naïve hawkmoths of two species in a wind tunnel, presenting an odour source and a visual stimulus. ... The nocturnal Deilephila elpenor responded preferably to the odour while the diurnal Macroglossum stellatarum strongly favoured the visual stimulus.
Note: Deilephila elpenor = elephant hawk-moth (common name, not in the abstract) - The page saysThe researchers suggest bright daylight made sight more useful than smell.
- The source says
During bright daylight visual cues may have became more important than odour.

Herrera 1992
Herrera (1992). Activity pattern and thermal biology of a day-flying hawkmoth (Macroglossum stellatarum) under Mediterranean summer conditions. Ecological Entomology.
- The page saysIn foraging moths at a flowering lavender patch in southeastern Spain, the thorax, the middle section of the body, stayed between 39 and 46 degrees Celsius while the air ranged from 19 to 36 degrees.
- The source says
Foraging took place over a broad range of microclimatic conditions, as described by air temperature ( T a ; range 19‐36°C) and solar radiation (IR; range 1–1025 Wm ‐2 ). The thoracic temperature ( T th ) of insects remained within relatively narrow limits (39–46°C)
Note: lavender = Lavandula latifolia, named in the abstract: 'foraging at a flowering population of Lavandula latifolia (Labiatae) under the dry‐hot summer conditions of a southeastern Spanish locality' - The page saysThe author called their tolerance of high thorax temperature unusual.
