Herbivore handling of a Plant’s trichome: the case of Heliconius charithonia (L.) (Lepidoptera: Nymphalidae) and Passiflora lobata (Killip) Hutch. (Passifloraceae) Neotropical Entomology
Cardoso,Márcio Z..
Trichomes reduce herbivore attack on plants by physically and/or chemically inhibiting movement or other activities. Despite evidence that herbivores are negatively affected by trichomes there also reports of insect counter-adaptations that circumvent the plant’s defense. This paper reports on a study that investigated the likely mechanisms employed by larvae of the nymphalid butterfly, Heliconius charithonia (L.), that allow it to feed on a host that is presumably protected by hooked trichomes (Passiflora lobata (Killip) Hutch). Evidence were gathered using data from direct observations of larval movement and behavior, faeces analysis, scanning electron microscopy of plant surface and experimental analysis of larval movement on plants with and without...

Nest and egg description of threatened Herpsilochmus spp. from coastal forest habitats in Rio Grande do Norte, Brazil (Aves: Thamnophilidae) Zoologia
Silva,Marcelo da; Pichorim,Mauro; Cardoso,Márcio Z..
We provide description of eggs and nest structure for two Brazilian antwrens, including the IUCN "vulnerable" species, H. pectoralis Sclater, 1857, and the BirdLife International "near-threatened", H. sellowi Whitney & Pacheco, 2000. Our observations derive from a larger study on Herpsilochmus Cabanis, 1847 distribution in coastal forest fragments in the northern range limit of the Brazilian Atlantic rainforest. Both species nested in relatively open forest. The nest of H. sellowi was built with fungal hyphae, a trait common among some birds. Both eggs were moderately beige with brown spots. Most of the information on Brazilian antwren nesting comes from species that do not occur in the Atlantic rainforest. This is the first account for nest...

New localities for Heliconius besckei Ménétriés and Heliconius sara (Fabricius) (Lepidoptera: Nymphalidae) in Bahia, Brazil Neotropical Entomology
Cardoso,Márcio Z..
New occurrences for two Heliconius Kluk species are reported for sites in inland Bahia, Brazil. New inland sites are reported for Heliconius sara (Fabricius), a species normally found at coastal regions. To our knowledge, Heliconius besckei Ménétriés, a species restricted to cool mountain habitats, is reported for Northeastern Brazil for the first time.
