Eumacaria
genus of insects
Eumacaria is a monotypic moth genus in the family Geometridae described by Packard in 1873. Its only species, Eumacaria madopata, the brown-bordered geometer moth, was first described by Achille Guenée in 1857. It is found in North America, where it has been recorded from British Columbia, northern Washington, southern Saskatchewan, from Maine to Florida, South Dakota, North Dakota, Nebraska, Wyoming, Idaho, Colorado and New Mexico. The habitat consists of orchards and shrublands. The species is listed as threatened in Connecticut.
The wingspan is 20–25 mm. Adults are on wing from early June to early July in the north and from April to September in the south. There is one generation per year.
The larvae feed on Prunus species (including Prunus pensylvanica and Prunus serotina) as well as Pyrus.

The public source identifies “Eumacaria” as genus of insects. This brief keeps that definition visible, then builds a research path around Eumacaria, genus and insects.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Eumacaria”, the useful work is to connect “genus of insects” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 15, 2026. The linked authority identifier is Q5409523. The first chronological checks are 1873 and 1857.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
