Gracillariidae is an important family of insects in the order Lepidoptera and the principal family of leaf miners that includes several economic, horticultural or recently invasive pest species such as the horse-chestnut leaf miner, Cameraria ohridella.
Baltic amber or succinite is amber from the Baltic region, home of its largest known deposits. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that this forested region provided the resin for more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014 and 400 tonnes in 2015.
Stigmellites is a genus of Lepidopteran fossils. It is only known from trace fossils of leaf mines.
Psyllototus is an extinct genus of flea beetles described from the late Eocene Rovno amber of Ukraine, and from the Baltic amber of Russia and Denmark. It was named by Konstantin Nadein and Evgeny Perkovsky in 2010, and the type species is Psyllototus progenitor. In 2016, a newly described extant flea beetle genus from Bolivia, Chanealtica, was found to be most similar to Psyllototus, based on the characters available for observation.
Glisachaemus is an extinct monotypic genus of planthopper in the Cixiidae subfamily Cixiinae and at present, it contains the single species Glisachaemus jonasdamzeni. The genus is solely known from the Early Eocene Baltic amber deposits in the Baltic Sea region of Europe.
The Lepidoptera fossil record encompasses all butterflies and moths that lived before recorded history. The fossil record for Lepidoptera is lacking in comparison to other winged species, and tending not to be as common as some other insects in the habitats that are most conducive to fossilization, such as lakes and ponds, and their juvenile stage has only the head capsule as a hard part that might be preserved. Yet there are fossils, some preserved in amber and some in very fine sediments. Leaf mines are also seen in fossil leaves, although the interpretation of them is tricky. Putative fossil stem group representatives of Amphiesmenoptera are known from the Triassic.
Paleolepidopterites is a collective genus of fossil moths which can not be placed in any defined family. The included species were formerly placed in the leaf-roller family Tortricidae and are known from fossils found in Russia and the United States. The collective genus contains three species: Paleolepidopterites destructus, Paleolepidopterites florissantanus, and Paleolepidopterites sadilenkoi, formerly placed within the genera Tortrix and Tortricites respectively. The three species were formally redescribed and moved to the new collective genus by Heikkilä et al. (2018).
Epiborkhausenites is an extinct genus of moth in the concealer moth family Oecophoridae and containing a single species Epiborkhausenites obscurotrimaculatus. The species is known only from Middle Eocene, Bartonian stage, Baltic amber deposits near the town of Palanga in Lithuania.
Elephantomyia (Elephantomyia) baltica is an extinct species of crane fly in the family Limoniidae. The species is solely known from the Middle Eocene Baltic amber deposits in the Baltic Sea region of Europe. The species is one of six described from Baltic amber.
Elephantomyia (Elephantomyia) brevipalpa is an extinct species of crane fly in the family Limoniidae. The species is solely known from the Middle Eocene Baltic amber deposits in the Baltic Sea region of Europe. The species is one of six described from Baltic amber.
Electromyrmex is an extinct genus of ants in the formicid subfamily Dolichoderinae. The genus contains a single described species, Electromyrmex klebsi and is known from a group of Middle Eocene fossils which were found in Europe.
Rovno amber, occasionally called Ukrainian amber, is amber found in the Rivne Oblast and surrounding regions of Ukraine and Belarus. The amber is dated between Late Eocene and Early Oligocene, and suggested to be contemporaneous to Baltic amber. Major exploration and mining of the amber did not start until the 1990s.
