The gypsy moth is native to a vast area of Eurasia. The established North American population originated from near Paris, France, and was introduced into Medford, Massachusetts, in 1869 (Ferguson 1978). Adult gypsy moths do not feed. The larvae are dark with sparse, stiff hairs and a pattern of red and blue dorsal spots. Please see any relevant pamphlet or Web site (e.g., Forest Service specific site) for an illustration. Gypsy moth caterpillars often rest in groups in crevices, etc., but they do not make a communal tent and are solitary feeders. Such tents in spring are made by eastern tent caterpillars on wild cherries and other species of Prunus , Malus , and Crataegus . The unrelated, dissimilar tent caterpillars are routinely mistaken for gypsy moth larvae by the uninformed public and sometimes by TV news crews. Unlike most Noctuoidea, gypsy moths pupate neither in the soil nor in a substantial cocoon. The dark, reddish-brown pupa is attached to NatureServe Gypsy Moth: Impacts and Options for Biodiversity-Oriented Land Managers 7 various objects in a minimal silk cocoon through which it is fully visible. The presence of obvious golden hairs on it will separate the pupae from almost all others. Usually a somewhat sheltered location is chosen for pupation. Gypsy moth eggs overwinter and hatch during warm weather in spring, usually soon after oaks begin to leaf out but a few days later than many native spring caterpillars. There is only a single annual generation in all parts of its range. First instar larvae can disperse via the wind on warm, sunny days and commence feeding once they find an acceptable plant. The great majority of hatching occurs in a 1-week period (Schweitzer, pers. obs.; Doane and McManus 1981, pp. 184-186), but it can spread out over a month with egg masses in the sunniest places hatching earlier.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
