  • A = Abundant (likely to be seen in Sligo, often in numbers, on any given day during most or all of the butterfly season [Mar-Oct])
  • C = Common (likely to be seen in Sligo on most days during a significant portion of the butterfly season)
  • U = Uncommon (not frequently seen in Sligo and/or restricted to a short flight period)
  • R = Rare (likely to be seen in Sligo only a few times during the butterfly season).
Note that butterfly abundance can, and usually does, vary dramatically from year to year.
Butterfly checklist (45 species) for section 3 of Sligo Creek Park (Maple Ave. to Piney Branch Rd.), compiled by Jason Hall, Sligo watershed resident and research entomologist with the Smithsonian Institution, specializing in neotropical butterflies. The checklist was compiled between 2006 and 2009, with species recorded from the natural habitats of the Park itself and from the gardens of homes immediately bordering the Park. These gardens harbor a wide variety of food plants (for caterpillars) and nectar sources (for butterflies) that are critical to maintaining the populations of many of the Park’s butterfly species.
