Aximopsis gabrielae Zhang, Gates and Campos sp. nov. is described from southern Mexico in the Yucatan Peninsula, Mexico. This species is a koinobiont gregarious larval-pupal endoparasitoid of the caterpillar of Quadrus cerialis (Stoll) (Lepidoptera: Hesperiidae) feeding on the shrub Piper amalago L. (Piperaceae) in the semievergreen forest. This is...

Myrmecophilous butterflies can establish complex symbiotic relationships with ants. A caterpillar wandering among the brood of the aggressive ponerine ant Neoponera villosa was found inside the core of a nest built in the myrmecophytic bromeliad Aechmea bracteata. This is the first caterpillar found living inside a ponerine ant nest. Its DNA barcod...

Myrmecophilous butterflies can establish complex symbiotic relationships with ants. An elusive symbiotic caterpillar wandering among the brood of the aggressive ponerine ant, Neoponera villosa, was found inside the core of a nest built in the myrmecophytic bromeliad Aechmea bracteata. This is the first caterpillar found in symbiosis with a species...

Los plátanos son una de las frutas privilegiadas en la dieta humana y varias de sus especies también son ornamentales por la belleza de sus inflorescencias, aunque este aspecto no es tan conocido. Su procedencia del Asia tropical era vox populi, pero la historia evolutiva ha rastreado el linaje de los bananos silvestres en otra dirección.

In the Yucatan Peninsula, the ponerine ant Neoponera villosa nests almost exclusively in tank bromeliads, Aechmea bracteata. In this study, we aimed to determine the factors influencing nest site selection during nest relocation which is regularly promoted by hurricanes in this area. Using ants with and without previous experience of Ae. bracteata,...

We conducted a biogeographic analysis of Musaceae, emphasizing the importance of the fossil record to understand the early evolutionary history of the family. Molecular dating and integration of biogeographic reconstructions suggest a boreotropical origin for Musaceae across the landmasses of North America+Europe+Asia. We hypothesize that North Ame...

Fragmentation is the third cause of the biodiversity declination. Population genetic studies using Lepidoptera as the model species in the context of loss of habitat are scarce, particularly for tropical areas. We chose a widespread butterfly from Mexico as the model species to explore how changes of habitat characteristics (undisturbed forest, ant...
