As identifiers work through observations stuck at Life or Unknown, it is common to find recurring species that often look mysterious. The aim for this project is to collect helpful "reference observations" for commonly mis/unidentified species, to make from-Life identification of these species easier. Such mysteries can be found in any kingdom.

For best effect, observations you submit to this project should carry high confidence to be the particular species in question. Observations with clear and/or multiple angles of the species' diagnostic features are encouraged.
