Anatomy and ontogenesis of hymenopteran
leaf galls of Struthanthus vulgaris Mart.
Parasitoids that emerged during this study are Chalcidoidea hymenopterans
belonging to six families (Table 5).
A braconidaeous hymenopteran
(visitor-2) in lateral view.
Among the common predaceous hymenopteran
taxa observed in this study were Trypoxylon tridentatum (Crabronidae), a spider-provisioning specialist (Coville, 1986); Isodontia elegans (Sphecidae), a species that provisions with paralyzed Orthoptera (O'Neill and O'Neill, 2007); and two species of eumenines, Euodynerus foraminatus (Stahlhut and Cowan, 2004) and Parancistrocems mcclayi.
The branches specific for coleopteran, hymenopteran
, dipteran, lepidopteran, and crustacean PPOs, respectively, are shaded in squares.
In heterogeneous environments such as tropical forest, using multiple sampling methods is recommended for assessing the diversity of hymenopteran
parasitoids (Noyes 1989).
To investigate how pollinators perceive these colors we employed two physiological models of trichromatic hymenopteran
While calyptrate dipteran flies were consistently diverse and abundant throughout the study, hymenopteran
(bee) taxa varied in abundance from pre- through post-bloom.
Abstract.-This study provides an update to the endemic biota of Arkansas by adding 19 species to the state list, including two fungi, three gastropods, one araneid, two opilionids, two pseudoscorpions, one diplopod, three collembolans, two trichopterans, one coleopteran, one dipteran and one hymenopteran
. In addition, seven species (one pseudoscorpion, one collembolan, one bivalve, one ephemeropteran, and three trichopterans) are removed from the state list and a synthesis of new distributional records and changes in nomenclature are provided for several species.
