Exploración Morfológica del Corion en Biblidinae (Lepidoptera: Nymphalidae): Aspectos Filogenéticos y Clasificatorios

1AbstractThe evolution of organism size is hypothesized to be predicted by a combination of development, morphological constraints, and ecological pressures. However, tests of these predictions using phylogenetic methods have been limited by taxon sampling. To overcome this limitation, we generated a database of more than ten thousand observations of insect egg size and shape from the entomological literature and combined them with published genetic and novel life-history datasets. This enabled us to perform phylogenetic tests of long-standing predictions in size evolution across hexapods. Here we show that across eight orders of magnitude in egg volume variation, the relationship between egg shape and size itself evolves, such that predicted universal patterns of scaling do not adequately explain egg shape diversity. We test the hypothesized relationship between size and development, and show that egg size is not correlated with developmental rate across insects, and that for many insects egg size is not correlated with adult body size either. Finally, we show that the evolution of parasitism and aquatic oviposition both help to explain the diversification of egg size and shape across the insect evolutionary tree. Our study challenges assumptions about the evolutionary constraints on egg morphology, suggesting that where eggs are laid, rather than universal mathematical allometric constants, underlies egg size and shape evolution.

“…Además, algunas hembras del grupo se observaron en estratos medios y altos, asociadas a la búsqueda de sitios óptimos con plantas hospederas para la ovoposición, lo que puede aumentar las distancias de desplazamiento. Por otro lado, las hembras permanecen un menor tiempo en las zonas con respecto a los machos, debido a que muchas estarían en la búsqueda de recursos fundamentales para el proceso de maduración de huevos como sales, nutrientes, ácido úrico y azucares (Baker, 1972;Gilbert, 1975;Gilbert y Singer, 1975;Jones, 1884;Nieves et al, 2015;Sterry, 1997).…”

Los estudios poblacionales de mariposas en el Caribe colombiano son escasos, razón por la cual se analizó la estructura poblacional y el desplazamiento de Hamadryas Hübner (1806) en diferentes usos del suelo en un paisaje fragmentado en los Montes de María, San Jacinto, Bolívar. Se realizaron 6 muestreos entre marzo y junio de 2018. En el área de estudio se ubicaron 7 estaciones donde se colocaron 5 trampas Van Someren-Rydon cebadas con mezcla de fruta fermentada. Mediante el método de captura-marcaje-recaptura, se registraron 541 individuos del género Hamadryas (312 machos - 229 hembras). La especie más abundante fue H. feronia (Linnaeus, 1758) con 291 individuos registrados y la menos frecuente H. amphinome (Linnaeus, 1767) con 33 registros. Las proporciones sexuales variaron, aunque el número de machos siempre fue mayor y las hembras experimentaron una mayor distancia de desplazamiento. La estructura de edades y las recapturas mostraron un pico de emergencia de imagos entre abril-junio. Por último, la variación de la abundancia de Hamadryas se asocia, principalmente, con la cobertura del dosel, indicando que este factor juega un papel determinante en la dinámica poblacional de este grupo de mariposas.

“…Many species lay their eggs singly in widely spread manner, in tiny clumps or in masses, while others lay the egg masses which are further coated by a hardened fluid from the female's abdomen glands (Holland, 1898;1903). The taxonomic and phylogenetic significance of egg shell architecture has been demonstrated in several lepidopteran families-Noctuidae (Salkeld, 1984), Lycaenidae (Munguira et al, 2015), Danaidae (Kitching, 1985), Mnesarchaeidae (Kobayashi and Gibb 1995), Rougerie and Estradel 2008), Pieridae (Llorente-Bousquets and Castro-Gerardino 2007;Llorente-Bousquets et al, 2018;Hernández-Mejía et al, 2013), Nymphalidae (García- Barros and Martín, 1995;Freitas and Brown, 2004;Nieves-Uribe et al, 2015) and others.…”

The identification of moths has been always dependent on characters like wing maculation, wing venation, male and female genitalic features, but the ultrastructural characters like egg chorion patterns have been completely ignored. These are equally important for identification. In the present study, scanning electron microscope was used to inspect, characterize, and depict eggs of two tiger moth species i.e., Andala unifascia Walker, 1855 and Creatonotos transiens (Walker, 1855) referable to family Erebidae. On the eggshells of both these species, morphological features have been observed and these are of great taxonomic value at species as well as at genus levels. These characters will enable identifying moths at much earlier stages of their life histories i.e., eggs.
