Bradysia
Bradysia is a genus of fungus gnat in the family Sciaridae. They are commonly known as darkwinged fungus gnats. They are considered a major pest in greenhouse agriculture because they thrive in the moist conditions common inside greenhouses and feed on the plants being grown within. Bradysia is a large genus containing over 500 living species, with at least 65 species found in North America and 172 in Europe.

Time the record covers
At least 27 million years on record.
The record covers at least 27.3 Mya to 129 ka. No occurrence read is dated outside 33.9 Mya to 11.7 ka.
13 occurrences of Bradysia on record, most of them in the Miocene. The Paleobiology Database records this as a living group. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
13 occurrences- Oligocene15%
- Miocene77%
- Pleistocene8%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 10 sites for Bradysia, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Each of the 13 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
