Movements and morphology under sexual selection: tsetse fly genitalia
Briceño Lobo, Daniel; Wegrzynek, D.; Chinea Cano, E.; Eberhard Chabtree, William G.; Dos Santos Rolo, T. (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 ... -
The mystery of how spiders extract food without masticating prey
Eberhard Chabtree, William G.; Barrantes Montero, Gilbert (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 ... -
Ontogeny repeats phylogeny in Steatoda and Latrodectus spiders
Barrantes Montero, Gilbert; Eberhard Chabtree, William G. (2010)Web designs of young spiders are often less derived than those of older conspecific individuals. This study tested whether this ‘‘ontogeny repeats phylogeny’’ pattern occurs in two species of Latrodectus and two species ... -
Possible Fisherian Changes in Female Mate-Choice Criteria in a Mass-Reared Strain of Ceratitis capitata (Diptera: Tephritidae)
Briceño Lobo, Daniel; Eberhard Chabtree, William G. (Annals of the Entomological Society of America Vol. 93, no. 2, 343-345, 2000)The frequent interruption of male courtship in highly crowded mass-rearing cages of Ceratitis capitata (Wiedemann) was correlated with changes in both male courtship and female acceptance criteria in a mass-reared Costa ... -
Seasonal patterns of parasitism of the tropical spiders Theridion evexum (Araneae, Theridiidae) and Allocyclosa bifurca (Araneae, Araneidae) by the wasps Zatypota petronae and Polysphincta gutfreundi (Hymenoptera, Ichneumonidae)
Barrantes Montero, Gilbert; Eberhard Chabtree, William G.; Weng, Ju Lin (2008)Las tasas de parasitismo de Theridion evexum por la avispa parasitoide Zatypota petronae y de Allocyclosa bifurca por Polysphincta gutfreundi fueron estudiadas durante dos años. El parasitismo en T. evexum fue muy bajo ... -
The hub as a launching platform: rapid movements of the spider Leucauge mariana (Araneae: Tetragnathidae) as it turns to attack prey
Briceño Lobo, Daniel; Eberhard Chabtree, William G. (The Journal of Arachnology arac-39-01-13.3d 22/12/10 13:25:38 1 Cust # Hi10-76, 2011)Spiders are effectively blind with respect to the lines in their webs, and they commonly use exploratory leg movements to find lines, just as a blind man finds objects using a cane. Nevertheless, a mature female Leucauge ... -
Tie them up tight: wrapping by Philoponella vicinaspiders breaks, compresses and sometimes kills their prey
Eberhard Chabtree, William G.; Barrantes Montero, Gilbert; Weng, Ju Lin (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 ... -
Variation in the intermittent buzzing songs of male medflies (diptera: tephritidae) associated with geography, mass-rearing, and courtship success
Briceño Lobo, Daniel; Eberhard Chabtree, William G.; Liedo, P.; Shelly, Todd; Vilardi, Juan (Florida Entomologist 85(1) March 2002, 2002-03)Varios aspectos de los patrones temporales de los sonidos del zumbido intermitente producido durante el cortejo pre-copulatório de los machos de la mosca del Mediterráneo variaron entre moscas silvestres de Costa Rica, ... -
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)
Eberhard Chabtree, William G.; Barrantes Montero, Gilbert; Madrigal Brenes, Ruth (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 ...
