Recent studies suggest tha. the energetic dema.ds of long-dista.ce migra.ion might lower the pool of resources a.a.la.le for costly immune defenses. Moreover, migra.ion could a.plify the costs of pa.a.itism if a.ima.s suffering from pa.a. site-induced da.a.e or depleted energy reserves a.e less a.le to migra.e long dista.ces. We investiga.ed rela.ionships between long-dista.ce migra.ion, infection, a.d immunity in wild fa.l-migra.ing mona.ch butterflies da.a.s plexippus. Mona.chs migra.e a.nua.ly from ea.tern North a.erica.to centra. Mexico, a.cumula.ing lipids essentia. for migra.ion a.d winter surviva. a. they tra.el southwa.d. Mona.chs a.e commonly infected by the debilita.ing protozoa. pa.a.ite Ophryocystis elektroscirrha.（OE）. We collected da.a.on lipid reserves, pa.a.ite loa.s, a.d two immune mea.ures （hemocyte concentra.ion a.d phenoloxida.e a.tivity） from wild mona.chs migra.ing through north Ga.（USa. to a.k whether （1） pa.a.ite infection nega.ively a.fects lipid reserves, a.d （2） grea.er investment in lipid reserves is a.socia.ed with lower immune mea.ures. Results showed tha. mona.chs sa.pled la.er in the fa.l migra.ion ha. lower but not significa.tly different immune mea.ures a.d significa.tly higher lipid reserves tha. those sa.pled ea.lier. Lipid mea.ures correla.ed nega.ively but only nea.ly significa.tly with one mea.ure of immune defense （phenoloxida.e a.tivity） in both hea.thy a.d infected mona.chs, but did not depend on mona.ch infection sta.us or pa.a.ite loa.. These results provide wea. support for a.tra.e-off between energy reserves a.d immune defense in migra.ts, a.d suggest tha. previously-demonstra.ed costs of OE infection for mona.ch migra.ion a.e not ca.sed by depleted lipid reserves .
