Psychodinae

The Psychodinae are the nominate subfamily of moth flies (Psychodidae), also known as drain flies. Like most of their relatives, they are usually found in damp habitats; some occur in caves. The small larvae are aquatic or semi-terrestrial; the adults are winged and capable of flight. Psychodinae are found worldwide, including some subantarctic islands.

Time the record covers

At least 128 million years on record.

The record covers at least 149.2 Mya to 20.45 Mya. No occurrence read is dated outside 161.5 Mya to 13.82 Mya.

77 occurrences of Psychodinae on record, most of them in the Eocene. The Paleobiology Database records this as a living group, and the chart stops with its fossils rather than at the present. 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

77 occurrences

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.

3,329 taxa

The Paleobiology Database records 47 sites for Psychodinae, 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.

Entered from

25 references

Each of the 77 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. 13 further references are not listed. 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.
