Dasyhelea

Searched as Dasyhelea australis antiqua. The Paleobiology Database treats Dasyhelea as the accepted name.

Dasyhelea is a genus of biting midges and the only genus of its subfamily, the Dasyheleinae. Larvae of species in this genus are characterized by an anal segment with retractile posterior prolegs. Larvae are aquatic and adults do not feed on vertebrate blood, nor do they prey on other insects. They take nectar only, an unusual feeding behavior within the Ceratopogonidae.

Time the record covers

At most 2.2 million years on record.

The one occurrence read is dated to somewhere between 18.5 Mya and 16.3 Mya, which is a dating window rather than a span.

1 occurrence of Dasyhelea on record, most of them in the Miocene. 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

1 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.

The Paleobiology Database records 56 sites for Dasyhelea, 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

1 reference

Each of the 1 occurrence 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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
