Nymph Anatomy and Instar Determination

2019
Knowledge of the external anatomy of Odonata nymphs is necessary for learning how to use the keys for identification. Basic morphology and terminology of all structures crucial for identification of Anisoptera nymphs to family, genus and species are described and illustrated in detail beginning with orientation of the dragonfly nymph body and the basic

Cannibalism and early instar survival in a larval damselfly

Oecologia, 1994
Cannibalism by larval damselflies late in larval development on larvae a few instars smaller has been widely documented. I examine here the survival of eggs oviposited near the end of the flight season of adult Enallagma boreale in the presence and absence of potential cannibals, individuals that hatched from eggs earlier in the season, over an ...

Photoresponses of second-instar Chaoborus larvae

Journal of Insect Physiology, 1982
Abstract The diel vertical migration of Chaoborus larvae varies with larval instar. Although light is involved in the control of vertical migration the contribution of larval photoresponses is unknown. In order to describe ontogenetic changes in larval photoresponses we measured photoresponses of second-instar Chaoborus punctipennis larvae in the

A Note on the Use of the Terms Instar and Stage1

Annals of the Entomological Society of America, 1978
The terms instar and stadium are not synonymous. An instar forms at the moment of apolysis or as soon as the 1st layer of a new cuticle is laid down underneath the old one. This period in the insect's life is always initially concealed. A stadium begins at the moment of ecdysis, when the instar emerges from either an egg shell, an old larval cuticle ...

Morphology of juvenile instars of Ameronothridae (Acari: Oribatida)

Zootaxa, 2012
Juvenile instars of four species of the oribatid mite family Ameronothridae— Alaskozetes antarcticus intermedius, Amer-onothrus lineatus, Halozetes crozetensis and Pseudantarcticola georgiae—are described and illustrated in detail. Knownjuvenile instars of the family are compared, new diagnoses are given when possible, and identification keys to genera

Copepod Instar Survival and Predation by Zooplankton

Journal of the Fisheries Research Board of Canada, 1977
The survivorship of each instar of three cohorts of Leptodiaptomus minutus from Bluff Lake, Nova Scotia, is presented. High naupliar mortality but low copepodite mortality occurred. The previously reported values for the predation rate and size selection of prey by omnivorous zooplankton are compared with the observed mortality rates for the different

The Problem of Instar Numbers in Arthropods

2011
The last 20 years the distribution of computing power to individuals through personal computers and the subsequent explosion in the production of scientific software dramatically changed the scientific work. The initial availability of expensive statistical software was replaced by inexpensive commercial packages – i.e., SPSS, SYSTAT, SAS, CART among ...

INSTAR DIFFERENTIATION IN LARVAL CHIRONOMIDAE (DIPTERA)

The Canadian Entomologist, 1974
AbstractExamination of the most commonly used criteria for separating instars in larval chironomids, based on a study of 29 species from three subfamilies in Marion Lake, British Columbia, revealed that only head capsule width or length is suitable. Most chironomids appear to have four larval instars.
