Kaliningrad District, Russia
Description: This amber piece displays an uncommonly
large example of a member of the Diptera. The term Diptera means
“two-winged” and is actually a misnomer. Most members
have a second, vestigial pair of wings that are mere knobs which
are used as a “gyroscope” to keep the insect level in
flight. This one is a dark-winged fungus gnat which, unlike many
Baltic inclusions, is readily visible to the unaided human eye.
The larvae of fungus gnats feed upon decaying vegetation, hence
the common name.
