Abstract:
Food plants and information on life history are presented for six species of Argidae and four species of
Tenthredinidae in Costa Rica. #e Argidae include cocoons of Atomacera josefernandezi Smith, sp. n.,
found on Hampea appendiculata (Donn. Sm.) Standl. (Malvaceae) and likely feeding on its leaves before
pupation, and larvae of Eriglenum tristum Smith feeding on Machaerium seemanii Benth. Ex Seem. (Fabaceae),
Ptenos leucopodus (Cameron) feeding on Inga oerstediana Benth. and I. vera Willd. (Fabaceae),
Ptilia peleterii (Gray) feeding on Cnestidium rufescens (Connaraceae), and Scobina lepida (Klug) and S.
notaticollis (Konow) feeding on Sida rhombifolia L. (Malvaceae). #e Tenthredinidae include larvae of
Dochmioglene crassa (Cameron) feeding on the fern Lomariopsis vestita E. Fourn. (Lomariopsidaceeae),
Dochmiogleme Smith03 feeding on Blechnum occidentale L. (Blechnaceae), Waldheimia laeta (Cameron)
feeding on Cissus alata Jacq. (Vitaceae), and Waldheimia lucianocapellii Smith, sp. n., feeding on Davilla
nitida (Vahl) Kubitzki (Dilleniaceae). Waldheimia lucianocapellii is described from specimens from both
Panama and Costa Rica. Selandria crassa Cameron, 1883 is a comb. n. in Dochmioglene.
