“…Butterflies of the subfamily Ithomiinae (Nymphalidae) are diverse members of Neotropical forests (DeVries 1987). Their larvae feed on plants in the families Solanaceae and Apocinaceae, and the genus Hyposcada feeds on Gesneriaceae (DeVries 1987; Costa 1999). Ithomiines are sensitive to microhabitat conditions (Willmott & Mallet 2004), especially to microclimate (Brown & Freitas 2002).…”

Determining the permeability of different types of landscape matrices to animal movement is essential for conserving populations in fragmented landscapes. We evaluated the effects of habitat patch size and matrix type on diversity, isolation, and dispersal of ithomiine butterflies in forest fragments surrounded by coffee agroecosystems in the Colombian Andes. Because ithomiines prefer a shaded understory, we expected the highest diversity and abundance in large fragments surrounded by shade coffee and the lowest in small fragments surrounded by sun coffee. We also thought shade coffee would favor butterfly dispersal and immigration into forest patches. We marked 9675 butterflies of 39 species in 12 forest patches over a year. Microclimate conditions were more similar to the forest interior in the shade-coffee matrix than in the sun-coffee matrix, but patch size and matrix type did not affect species richness and abundance in forest fragments. Furthermore, age structure and temporal recruitment patterns of the butterfly community were similar in all fragments, independent of patch size or matrix type. There were no differences in the numbers of butterflies flying in the matrices at two distances from the forest patch, but their behavior differed. Flight in the sun-coffee matrix was rapid and directional, whereas butterflies in shade-coffee matrix flew slowly. Seven out of 130 recaptured butterflies immigrated into patches in the shade-coffee matrix, and one immigrated into a patch surrounded by sun coffee. Although the shade-coffee matrix facilitated movement in the landscape, sun-coffee matrix was not impermeable to butterflies. Ithomiines exhibited behavioral plasticity in habitat use and high mobility. These traits favor their persistence in heterogeneous landscapes, opening opportunities for their conservation. Understanding the dynamics and resource requirements of different organisms in rural landscapes is critical for identifying management options that address both animals' and farmers' needs.

“…El conocimiento detallado de plantas hospederas permitiría proponer hipótesis más sólidas de distribución y diversificación de este grupo, ya que se considera que la interacción de las Ithomiini con sus plantas hospederas ha jugado un papel significativo en su diversificación (Willmott y Freitas 2006, Willmott y Mallet 2004. Sin embargo, con el conocimiento actual, esas hipótesis pueden ser prematuras (Costa 1999).…”

“…Un marco general del estado del conocimiento de plantas hospederas de las larvas Ithomiini se obtiene de los trabajos de Beccaloni et al (2008), Costa (1999), De Vries (1989, Drummond y Brown (1987), Willmott y Freitas (2006) y Willmott y Mallet (2007), y de las páginas de internet de Haber (2001) y Janzen y Hallwachs (2011), quienes han registrado plantas silvestres y cultivadas usadas por este grupo.…”

En el trópico se dispone de pocos datos de la mayoría de los organismos, incluyendo las mariposas, en aspectos claves de su ciclo de vida, sus plantas hospederas y factores explicativos de su diversidad y abundancia. El objetivo de este trabajo fue identificar las plantas hospederas de larvas Ithomiini (Lepidoptera) en agroecosistemas de café y evaluar el efecto de las variables: sistema de producción, área en bosque y diversidad de hospederas sobre la diversidad y abundancia de este grupo. En seis fincas de café de Fredonia (Antioquia), Colombia, se recolectaron plantas de las familias Apocynaceae, Gesneriaceae y Solanaceae, que fueron identificadas en los Herbarios HUA y MEDEL de Medellín. En las fincas se registraron los adultos observados en vuelo y se recolectaron huevos, larvas y pupas de Ithomiini de sus plantas hospederas para su cría en laboratorio, hasta la emergencia de adultos. Se determinó el porcentaje de sobrevivencia y mortalidad debida a parasitoidismo. Los datos de diversidad se analizaron por medio de un Análisis de Regresión de Poisson. En los agroecosistemas de café se registraron 27 especies vegetales y 27 mariposas adultas Ithomiini, en laboratorio, se criaron 326 individuos de ocho especies, recolectados sobre siete plantas de la familia Solanaceae. Dos plantas constituyen registros nuevos como hospederas de las especies de Lepidoptera: Solanum atropurpureum hospedera de Mechanitis menapis y Solanum deflexiflorum hospedera de Pteronymia picta y P. latilla. La diversidad de Ithomiini fue explicada por la diversidad de hospederas y por el sistema de sombrío.

“…In particular, we evaluate the accuracy of an equation that describes body weight as a function of the length by examining the residuals (i.e., the differences between the observed and the estimated values) of the regression analysis, and determine analytically the minimum time interval that must be maintained between consecutive measurements of individual caterpillars. (Costa 1991(Costa , 1999; frass were removed and leaves and moisture were replenished every other day. At intervals of 2-4 days larvae were measured (body length to the nearest 0.5 mm) and weighed (to the nearest 0.1 mg); at the end, we obtained 173 pairs of measurements (length and weight) for the 28 larvae (1-12 pairs of values per larva; length range: 2-27 mm; weight range: 0.2-241.5 mg).…”

RESUMO -Este trabalho usa dados de lagartas da borboleta neotropical Hypothyris ninonia daeta (Bdv.) (Nymphalidae: Ithomiinae) para demonstrar que medidas do comprimento do corpo podem ser empregadas como índice acurado do peso em estudos de crescimento larval. Também determina analiticamente o intervalo de tempo entre medições consecutivas para manter em níveis aceitáveis as chances de sobreposição nas estimativas (i.e., as chances de que lagartas de comprimentos diferentes tenham o mesmo peso). Os resultados mostram que o estudo do crescimento de insetos imaturos não é necessariamente um empreendimento restrito ao laboratório. Esse enfoque pode ser particularmente útil para estimar a taxa de crescimento de imaturos no campo, quando medidas mais acuradas não são possíveis ou mesmo desejáveis de se obter. PALAVRAS-CHAVE: Lepidoptera, crescimento de lagartas, Hypothyris, Ithomiinae, relação comprimento-peso.ABSTRACT -This work utilizes data for caterpillars of the Neotropical butterfly Hypothyris ninonia daeta (Bdv.) (Nymphalidae: Ithomiinae) to demonstrate that body length measurements can be used as an accurate index of weight in larval growth studies. It also determines analytically the time interval that must be maintained between consecutive measurements in order to keep within acceptable levels the chances of overlap in estimates (i.e., the chances that caterpillars of different lengths have the same weight). These results show that studying the growth of immature insects is not necessarily an exclusive laboratory enterprise. This approach may be particularly useful to estimate immature growth rate in the field, when more accurate measures are not possible or even desirable to obtain.

New records of larval hostplants for ithomiinae butterflies (Nymphalidae)

Abstract: Seventeen new records of larval hostplants are given for Ithomiinae butterflies (Lepidoptera: Nymphalidae) in southeastern Minas Gerais, and one in Brasília, DF. At the present state of knowledge, generalizations about larval feeding habits of these insects may be premature.
