Donacia

Donacia is a large genus of aquatic leaf beetles in the subfamily Donaciinae. Like other members of that subfamily, the beetles have densely pubescent undersides and long antennae. The genus is recognized by the truncate elytral apex and pubescent area above the procoxa. Adults are active and readily take flight. Adults feed on the upper epidermis of host plants; some may be pollen feeders. Larvae feed on the sap of submerged portions of aquatic plants, such as water lilies, sedges (Cyperaceae), Sagittaria (Alismataceae), Sparganium (Typhaceae), pond weed (Potamogeton). They are believed to breathe oxygen from plant vessels as well as cutaneously. Adults live on surface parts of the same plants but can go under water for extended periods because of their plastron.

Time the record covers

At least 61 million years on record.

The record covers at least 61.66 Mya to 129 ka. No occurrence read is dated outside 66 Mya to 11.7 ka.

143 occurrences of Donacia on record, most of them in the Pleistocene. 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

143 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 92 sites for Donacia, 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.

41 references

Each of the 143 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. 29 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.
