Sampling Methods for Dragonflies and Damselflies
2020Dragonflies and damselflies have become model organisms in ecological and evolutionary studies, mainly because they are considered flagship taxa for the conservation of water resources. Hence, how to standardize collection of odonates for the assessment of their diversity is an issue most researchers working with the group or the ecology of freshwaters

Consequences of ectoparasite infection in damselflies
2022Interspecific and intraspecific variation of parasitism can have different fitness costs between sexes and across developmental stages. This variation could arise because of individual differences in immunity and resistance. Theory predicts that the extent of parasitism and its costs will be greater in males than females.

Behavioral ecology of larval dragonflies and damselflies
Trends in Ecology & Evolution, 1991During the past decade, larval dragonflies and damselflies (Insecta: Odonata) have been the subjects for very productive ecological research. Descriptive field work, enclosure experiments and laboratory behavior studies have identified fish predation, intraguild predation (especially mutual predation among odonates, including cannibalism) and ...

Sperm Transfer in Damselflies (Odonata: Zygoptera)1
Annals of the Entomological Society of America, 1965Prior to copulation, male odonates transfer sperm from the genital pore on abdominal segment 9 to the accessory genitalia on segment 2, a type of behavior peculiar to this order of insects. Corbet (1963), considering the entire order, states that the time of transfer may vary between and within species, and lists the following times in the reproductive

PHYSIOLOGICAL COSTS OF COMPENSATORY GROWTH IN A DAMSELFLY
Ecology, 2006Little is known about physiological costs of rapid growth. We successfully generated compensatory growth to time stress and transient food stress in the damselfly Lestes viridis and studied the physiological correlates of the resulting reduced ability to cope with starvation.

Visual Target Detection in Damselflies
2009Abstract : Insect predators accomplish difficult visual tasks with tiny visual systems, and may provide important information for machine vision and remote sensing applications in variable light environments. We studied the visual system of the damselfly Megalagrion xanthomelas, which possesses 1.5mm diameter eyes with 360 degree field of view, lives ...

Female Choice in Damselflies and Dragonflies
2015Odonates have been frequently labeled as a taxa where males control female’s mating and fertilization decisions. Contrary to this position, in our contribution, we review instances where females can actually show choice of mates. Previous to mating, possible selected male traits are wing pigmentation, ability to defend oviposition sites , body color ...

Mating and Oviposition of Damselflies in the Laboratory
The Canadian Entomologist, 1965AbstractMethods and materials for colonizing damselflies (Ischnura) in the laboratory are described. Adults cease escape behavior in vision-proof cages. Females copulate only after first rejecting several would-be mates in succession and do not begin to oviposit until two to four hours afterwards.

Abstract This book is a collection of nineteen chapters where summaries of major ecological and evolutionary questions have been asked and responded using dragonflies and damselflies as study subjects. Each chapter is written by a well-respected scientist. The topics covered are: demography, population and community ecology, life-history,

Measuring Selection on a Population of Damselflies with a Manipulated Phenotype
Evolution, 1991The estimation of the relationship between phenotype and fitness in natural populations is constrained by the distribution of phenotypes available for selection to act on. Because selection is blind to the underlying genotype, a more variable phenotypic distribution created by using environmental effects can be used to enhance the power of a selection ...
