This is species is known in 30 countries. In Brazil, only one occurrence to this species is known located in the Northeast of Brazil according to GBIF database.


Population and Trends

There are 847 records in GBIF database, where 495 records to the United States of America, 74 to Canada, 51 to Mexico, and the other records are distributed in small percentages to the other countries.

Conservation Actions

In Brazil, the records are correlated to preserved areas that still affected by natural and unnatural influences, so formal education to the population that lives near those areas and the park managers can help to endorse the urge to effective preservation to those areas.
