Dragonflies and damselflies (Odonata) are insects with an important role for biological control environmental quality indicators. Odonata scattered in various types of habitats, especially those associated freshwater ecosystems. The aim this research is to study the diversity odonata habitat Leuwiliang District, Bogor Regency. was conducted on 10 a total 1289 observation lines. In found 23 spec...

Nanomaterials, specifically nano-topographies, have been explored for their antimicrobial activity toward bacteria, fungi and even viruses. A decade ago, we discovered that the nanopillar topography of insect wings such as cicadas, dragonflies damselflies, were not repelling bacteria previously surmised, but attaching consequently being killed. The nature bactericidal effect associated with nan...

We analysed a recently completed statewide odonate Atlas using multivariate linear models. Within a phylogenetically explicit framework, we developed a suite of data-derived traits to assess the mechanistic distributional drivers of 59 species of damselflies in New York State (NYS). We found that length of the flight season (adult breeding activity period) mediated by thermal preference drives ...

One explanation for hybridization between species is the fitness benefits it occasionally confers to the hybridizing individuals. This explanation is possible in species that have evolved alternative male reproductive tactics: individuals with inferior tactics might be more prone to hybridization provided it increases their reproductive success and fitness. Here we experimentally tested whether...

Females of coenagrionid damselflies exhibit color dimorphism, consisting of an andromorph and a gynomorph. This study compared reproductive traits between the female morphs in both field-captured and laboratory-reared females of the female-dimorphic damselfly Ischnura senegalensis. No difference was found in the onset of egg development between the morphs. The andromorphs developed significantl...
