The primeval moths (Micropterigidae) are a family of butterflies (Lepidoptera). They are the only family within the Zeugloptera, which represent the most primitive subordination of butterflies. They occur worldwide with approx. 100 kinds . They are very similar to the caddis flies (Trichoptera), to which the butterflies are most closely related. In contrast to them, however, the moths have scaled wings. The pupae are also more similar to those of caddis flies. The limbs, wings and antennae are not glued to the body, they are so-called free dolls ( pupa libera ) and not mummy dolls .
features
The moths reach a wingspan of 7 to 15 millimeters and have an elongated body shape. The forewings are 2.5 to 4 times longer than wide and are predominantly colored with a metallic sheen or at least have metallic patterns. The basic color is usually bronze or grayish bronze. The hind wings are about the same width as the fore wings and in some species have very long fringes. The moths have a conspicuous head of hair, which is also found in the families of the longhorn moths (Adelidae) and the trap moths (Eriocraniidae). The thread-like antennae are medium-long and about 0.6 to 0.9 times as long as the forewings. In addition to the compound eyes , the primeval moths also have two point eyes ( ocelli ). They are the only butterflies that instead of a suction pipe consisting of short chewing mouth parts maxilla and normal trained mandibles possess. They can use it to eat pollen . Their five-segment maxillary palps are well developed, their labial palps are only partially, in some species they are short or strongly regressed. All six legs are well developed and suitable for walking, and they have a double pair of spurs on the posterior sides of the tibia .
The wing veins of both wing pairs are the same: They each have 11 to 14 wing veins with two anal veins (1b and 1c).
The caterpillars have little in common with those of other butterfly caterpillars . They are white and have a pair of legs on each segment, which consist of a conical shaft that ends at a point. Thus, they are the only caterpillars with developed, real belly legs .
Way of life
The moths can be found on the flowers of herbs, shrubs and trees during the day.
Systematics
The primeval moth family is represented in Europe with 46 species, of which 15 species occur in Central Europe :
- Micropterix aglaella ( Duponchel , 1838) CH, D
- Micropterix allionella ( Fabricius , 1794) A, CH, D
- Micropterix aruncella ( Scopoli , 1763) A, CH, D
- Micropterix aureatella ( Scopoli , 1763) A, CH, D
- Micropterix aureoviridella ( Höfner , 1898) A, CH, D
- Micropterix calthella ( Linnaeus , 1761) A, CH, D
- Micropterix isobasella Staudinger , 1871 CH
- Micropterix mansuetella Zeller , 1844 A, CH, D
- Micropterix myrtetella Zeller , 1850 A
- Micropterix osthelderi Heath , 1975 A, CH, D
- Micropterix paykullella ( Fabricius , 1794) A, CH, D
- Micropterix rablensis Zeller , 1868 A
- Micropterix rothenbachii Frey , 1856 A, CH, D (Synonym: Micropteryx rothenbachii )
- Micropterix schaefferi Heath , 1975 A, CH, D
- Micropterix tunbergella ( Fabricius , 1787) A, CH, D
On December 15, 2015, the ORF reported online about the discovery of a new species:
- Micropterix gaudiella was newly discovered by scientists from the Tyrolean State Museums under the direction of Peter Huemer in the Bergamasque Alps , Italy. So far only 6 species of "primeval butterflies" restricted to the Alps were known. Gaudiella in the name from Latin gaudium expresses the joy of having found a 7th species.
The moth is only 7–8 mm tall and has a metallic gold and purple color. It bites and chews pollen with its chew and has been found on the flowers of roses and sun rose . It occurs at an altitude of 1600 m and only flies in sunshine.
Fossil evidence
The oldest confirmed fossil evidence of an ancient moth comes from Lebanon amber (approx. 130 million years, Lower Cretaceous ). The assignment of a much older insect from the Upper Triassic South Africa to this family is controversial. Other finds from the Cretaceous Period were made in Canadian, Burmese and Siberian amber , among others . In addition, representatives of this family can be found in the Eocene Baltic amber (40 to 50 million years old) and amber from the somewhat younger deposit near Bitterfeld . Under the amber inclusions there are both larvae and adults.
