Hairfly (Bibio): Insect remains are preserved only under exceptional
circumstances in an environment with no air present because their
exoskeleton (a hard outer casing) usually decomposes immediately after
death. That is why every new discovery of a fossil insect in Slovenia
is a special experience. The fossil insect depicting on the stamp was
discovered together with other fossils in grey marl slabs in the
Zasavje region and it belongs to the Diptera. The body is relatively
well preserved. One can see the thorax and head, the shape of which is
not very clearly recognisable. Also preserved is the front right leg.
Veins in the wings are clear, even though the wings are a little
damaged. Hairfly (Bibio) is an aquatic Diptera. It ended up in the mud
with little oxygen, which prevented effective bacterial decay and
promoted fossil preservation.
Aquatic insects served as the most important additional food for fish
and are therefore their fossil remains are frequently found in these
layers. The fossil depicting on the stamp forms a part of the Private
Paleontological collection Matija Križnar in Škofja Loka.
