Poisonous setae on a Baltic amber caterpillar

Arthropod Structure & Development, 2019
The knobbed setae on a small caterpillar in 45-55 million years old [Eocene] Baltic amber were studied and characterized as urticating, with evidence of liquid release implying the production of poisons. It is presumed that the caterpillar had been disturbed just prior to falling into the resin, as some of its setae showed defensive responses.

New Baltic amber Rhagionidae (Insecta, Diptera)

Palaeoentomology, 2023
A new species of Rhagionidae, Symphoromyia odileae, is described from the Middle Eocene Baltic amber. Chrysopilus meunieri Kerr, 2010, also from the Baltic amber, is redescribed on the basis of a new specimen, and its attribution to the genus Chrysopilus is confirmed.

Trichoptera from the Baltic Amber

1981
Caddis flies in Baltic amber are common. Since Ulmer’s extensive study — Die Trichopteren des Baltischen Bernsteins (1912) — 152 species belonging to 56 genera have been described. Our aim is to call attention again to the Baltic amber caddis flies and to reawaken interest in fossil Trichoptera.

The chemical composition of Baltic amber

Chemical Geology, 1984
Abstract The ether-soluble fraction of Baltic amber (Succinite) has been analyzed by capillary gas chromatography—mass spectrometry, and many diterpenoids of the abietane, pimarane and labdane series identified. Also found was a pattern of monoterpenoids similar to that encountered in fossil kauri resin, sesquiterpenoids and many other compounds ...

Identification of rumanite (Romanian amber) as thermally altered succinite (Baltic amber)

Physics and Chemistry of Minerals, 2000
Romanian amber (rumanite) has been considered to be a separate species of fossil resin for more than a century. While earlier investigators held it to be very similar to succinite (Baltic amber), modern scholars have assigned it a distinctly different botanical origin.

Trichoceridae (Dipt.) from the Baltic Amber

Insect Systematics & Evolution, 1971
AbstractSeveral amber collections have been surveyed for Trichoceridae and the two specimens, one male and one female, mentioned by Loew (I850:37) are here described under separate species in a new genus, Oligotrichocera. The systematic position of the family within the Tipuloidea is stressed.
