    • Cues guiding uloborid construction behavior support orb web monophyly 

      Eberhard Chabtree, William G.; Barrantes Montero, Gilbert (2015)
      Behavior can provide useful traits for testing phylogenetic hypotheses, and some details of orb web construction behavior have been especially useful in characterizing higher-level groups in spiders. The cues used to guide ...
    • Egg sac construction by folding dead leaves in Pozonia nigroventris and Micrathena sp. (Araneae: Araneidae) 

      Moya Ramírez, Jairo; Quesada Hidalgo, Rosannette; Barrantes Montero, Gilbert; Eberhard Chabtree, William G.; Escalante Meza, Ignacio; Esquivel Dobles, Carolina; Rojas, Andrés; Triana Cambronero, Emilia; Arias, Adriana (2010)
      Published descriptions of egg sac construction behavior in araneids are scarce. We describe egg sac construction and oviposition in one individual of the poorly known araneid Pozonia nigroventris (Bryant 1936) and two ...
    • Feeding by Philoponella vicina (Araneae, Uloboridae) and how uloborid spiders lost their venom glands 

      Weng, Ju Lin; Barrantes Montero, Gilbert; Eberhard Chabtree, William G. (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 

      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 ...
