Tie them up tight: wrapping by Philoponella vicinaspiders breaks, compresses and sometimes kills their prey
(2006)
We show that uloborid spiders, which lack the poison glands typical of nearly all other spiders, employ thousands of wrapping movements with their hind legs and up to hundreds of meters of silk line to make a shroud that ...
Movements and morphology under sexual selection: tsetse fly genitalia
(Ethology Ecology & Evolution 22: 385–391, 2010, 2010-04-17)
SHÖN (2009, Ethology Ecology & Evolution 21: 161–172) pointed out that in order
to understand the functional morphology of sexually selected structures that are used
as signaling devices in birds, it is crucial to ...
Vestiges of an orb-weaving ancestor? The “biogenetic law” and ontogenetic changes in the webs and building behavior of the black widow spider Latrodectus geometricus (Araneae Theridiidae)
(2008)
Young juveniles of L. geometricus fit the strong trend for “ontogeny to repeat phylogeny” previously documented in other web-building spiders; younger spiders were less likely to build the derived silk retreats that occur ...
Copulatory dialogue: female spiders sing during copulation to influence male genitalic movements
(Animal Behaviour, 2006, 72, 413-421, 2006)
Female behaviour during copulation that could function as communication with the male is probably more common than previously appreciated, but its functional significance remains little studied. Stridulation during copulation ...
La alometría estática de estructuras bajo selección sexual.
(2012-04-24)
El proyecto se diseñó para determinar la alometría del tamaño de las estructuras genitálicas y otras no-genitálicas en varias especies de Coleoptera. El informe es una lista de las publicaciones generadas a partir de la ...
The evolution of prey‐wrapping behaviour in spiders
(2007)
We traced the evolution of silk use by spiders in attacks on prey by combining previous publications with new observations of 31 species in 16 families. Two new prey‐wrapping techniques are described. One, in which the ...
Feeding by Philoponella vicina (Araneae, Uloboridae) and how uloborid spiders lost their venom glands
(2006)
Feeding by uloborid spiders is unusual in several respects: cheliceral venom glands are absent; prey wrapping is extensive (up to several hundred metres of silk line) and severely compresses the prey; the spider’s mouthparts ...
The mystery of how spiders extract food without masticating prey
(2006)
Standard accounts of how spiders obtain food without masticating their prey are probably largely wrong. Species in the families Uloboridae, Thomisidae, Araneidae and Theridiidae do not inject digestive fluid into the prey’s ...
Extreme Behavioral Adjustments by an Orb‐Web Spider to Restricted Spaces
(2012)
Adaptive flexibility in response to environmental variation is often advantageous and occurs in many types of traits in many species. Although the basic designs of the orb webs of a given species are relatively uniform, ...
Courtship behavior of different wild strains of Ceratitis Capitata (Diptera: Tephritidae)
(Florida Entomologist 90(1) March 2007, 2007-03)
Este estudio documenta diferencias en el comportamiento de cortejo de cepas silvestres de
Ceratitis capitata
(Wied.) provenientes de Madeira (Portugal), Hawaii (Estados Unidos de
Norte América), Costa Rica y Patagonia ...
