Helastia
Helastia is a genus of moths in the family Geometridae erected by Achille Guenée in 1868. It is considered by some to be a synonym of Larentia. This genus was redefined and described in 1987 by Robin C. Craw. This genus is endemic to New Zealand.

Time the record covers
At most 11 million years on record.
The one occurrence read is dated to somewhere between 93.7 Mya and 83.6 Mya, which is a dating window rather than a span.
1 occurrence of Helastia on record, most of them in the Late Cretaceous. 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- Late Cretaceous100%
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 1 site for Helastia, and this reads all of them. The number is how many of those sites it was catalogued from too.
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 referenceEach 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.
