Images in Ultraviolet (UV) Light
Highlights Page 1
Ref: black-tailed skimmer dragonfly imm male in uv.jpg
This Dragonfly has a blue power on the top surface similar to
the Broad Bodied Chaser, and shows similar (though in this
immature male not as developed) UV reflectance.
Photographed with permission from a protected private site, we
limited our handling to a minimum.
Ref: bluebell common (hyacinthoides non-scripta) in uv.jpg
The mature flower has quite high UV reflectance - a curse
of colour photography of this subject where filtering is
required to give the 'true' colour.
Ref: brimstone butterfly male 3 in uv.jpg
The top of the forewing shows unexpected patterning that
stops before the edge of the wing. See also different
individual male 4.
Ref: broad-bodied chaser dragonfly male in uv.jpg
This is the only commonly known member of the Odonata (Dragonfly &
Damselfly) family with substantial UV reflectance on the top
surface. It is a blue 'powder' that rubs off during life, so
old individuals often have less normal light blue and similar
The main section shows the female with none and
another male before and after brushing a segment
to show the effect.
We have also surveyed the Black-tailed Skimmer which shows
a similar characteristic.
Ref: buddleia - white colour in uv.jpg
The White buddleia is a very successful insect attractant,
and the brightness in UV may well contribute, more so when
insects have a choice than Lilac or yellow/orange vareties
which are near black in UV.
