The Valkyrie is a canard aircraft, equipped with a forewing
to prevent the plane from stalling in the air.
length: In male 34-35 mm (n = 4), in female 37-38 mm (n = 3).
The moth has black and creamy-white striped markings on its forewing
and a red, orange or yellow hindwing.
Morphology as well as diagnostic and functional significance of some structures (antennal sclerite, pronotal process, evaporatorial system, abdominal laterotergites, forewing
venation, femoral spine, female terminalia) are discussed.
The former species is distinguished from the new one by the course of the antemedian border of the medial area of the forewing
, slanted towards the tornus between the discal cell and the hind margin of the wing (compare pl.
bifidus with only a slight anteriolateral expansion, cubitus anterior 2 of the forewing
is piceous in T.
As the birds approach, bank and dive to decoys, the outstanding blue patch on each forewing
is a dead giveaway as to the identity.
A team of researchers at the University of Costa Rica has found that the beetles' metallic appearance is created by the unique structural arrangements of many dozens of layers of exo-skeletal chitin in the elytron, a hardened forewing
that protects the delicate hindwings that are folded underneath.
The costa on the forewing
was black and thickly overlaid with grayish or pinkish scales.
The bird-cherry ermine moth has several rows of black dots on its forewing
, and a wingspan of 16-25 mm.
hyaline, without dark transverse bands, and with only costal cell surrounded by strongly pigmented veins; marginal cell open; stigmal vein regularly curved, with distal part longer than proximal part.
He further diagnosed the sister group relationships of Hydrometrinae and Limnobatodinae based on the absence of ocelli, the body with spinous macrohairs, pronotal lobe with almost parallel sides; the forewing
venation reduced to two longitudinal veins and 1-2 crossveins; the abdominal tergum without paired, longitudinal ridges; the absence of an abdominal scent gland, and the egg shell with an open air-filled inner layer and outer plastron.
