The following is a list of plants which are recorded as being hostplants for butterflies found in the Washington, DC area. For the purpose of this list, the DC Area is defined as The District of Columbia, Arlington, Alexandria and Fairfax Counties in Virginia, and Montgomery and Prince George's Counties in Maryland. The information is gathered from various sources, and is intended to be as complete as possible. However, new butterfly hostplants are being reported all the time, and some existing records may later prove to be erroneous. This list includes only butterflies and plants reported as occuring in the Washington, DC area.

I have included information for the frequency of occurrence in the Washington, DC area for the butterflies listed. These should be used as rough guidelines. Keep in mind also that, while the flight period for a particular butterfly may extend only into May or June, the larvae may be found much later. Many larvae overwinter. Also, the flight periods listed are general. The butterfly may be seen flying slightly earlier or later than the given range, and there may be periods within each range when the butterfly is not on the wing, since it is between broods.

I have also listed the butterflies by current Scientific and Common names. Do not be surprised if the name differs from that in your field guide. Scientific and Common names do change, and undoubtedly many of the names on the list below will be obsolete in time.

Please also note that this list is not intended to give a complete listing of all recorded hostplants for a given species. I have tried to include only those plants which may be expected to occur in the Washington, DC area.

Each plant entry is followed by a list of Washington area butterfly species which are recorded as using that plant as a hostplant for its larvae. Plant names followed by (N) or (I) indicate that that plant is a "Native" or "Introduced" species to our area. A butterfly species listing followed by "(?)" indicates that that species is suspected of using that plant as a hostplant, but the relationship has not been verified.
