The Biology of Acroceridae (Diptera): True Endoparasitoids of Spiders

  title={The Biology of Acroceridae (Diptera): True Endoparasitoids of Spiders},
  author={Evert I. Schlinger},
The dipterous parasitoids and predators of spiders are restricted to a few families of Diptera and vary considerably in their mode of action. Members of the families Drosophilidae, Phoridae, Chloropidae, and Sarcophagidae are known to predate on eggs of several families of spiders (Clausen 1940; Eason et al. 1967). Recently, the first endoparasitic member of the family Tachinidae, Lypha sp., was reported to attack the fossorial spider Atypoides riversi in California (Vincent 1985). The only… 
First record of Epipompilus excelsus (Bradley, 1944) (Hymenoptera, Pompilidae) as a koinobiont ectoparasitoid of Ariadna mollis (Holmberg, 1876) (Araneae, Segestriidae)
It is demonstrated that the Neotropical species of E.excelsus, a parasitoid of the tube-dwelling spider Ariadnamollis, exhibits biological characteristics similar to the Australian species, acting as a koinobiont ectoparasitoid, but displays differences in larval morphology.
Diptera as predators and parasitoids of terrestrial gastropods, with emphasis on Phoridae, Calliphoridae, Sarcophagidae, Muscidae and Fanniidae.
The Diptera have become remarkably diverse ecologically, with some diversification in adult feeding behaviours, but, more significantly, a great range of media are utilized for development of the larval stages.
A review of fossil spider flies (Diptera: Acroceridae) with descriptions of new genera and species from Baltic Amber
This is the first comprehensive review of fossil spider flies (Diptera: Acroceridae), with morphological diagnoses and descriptions performed using modern cybertaxonomic tools and a dichotomous key to all fossil taxa of Acrocersidae are provided.
Death comes on two wings: a review of dipteran natural enemies of arachnids
Information is summarized on all lineages of Diptera known to attack arachnids, including predators, parasites, kleptoparasites and parasitoids, with particular emphasis on Acroceridae, one of the most significant groups of natural enemies of spiders.
Sinarachna nigricornis and genus-specific host utilization of Araneus spiders by the genus Sinarachna (Hymenoptera: Ichneumonidae)
The genus specificity of the cocoon web architecture described here, in which the typical cocoonweb exhibits a sparse but strong 3D architecture and in whichThe wasp cocoon is suspended by its apical end at the center, is expected for the genus Sinarachna.
Review of Chilean Cyrtinae (Diptera: Acroceridae) with the Description of Three New Species and the First Record of Villalus inanis from Argentina.
The aim of this study is to re-describe the known species of Holops and Villalus and describe three new Holops species based on collected material, which open the doors to disentangling the real biodiversity of spider flies in Chile.
Beobachtungen zur Parasitierung von Radnetzspinnen (Araneidae) durch Polysphincta rufipes (Hymenoptera: Ichneumonidae)
The ichneumonid Polysphincta rufipes Gravenhorst, 1829 is found to be a koinobiont parasitoid of two species of araneid orb-weavers, Larinioides sclopetarius and Zygiella x-notata, in Central Europe.
A associação de Philopota sp. Wiedemann (Diptera, Acroceridae) com flores do Gervão-Azul, Stachytarphetta cayenensis (Verbenaceae) na Ilha da Marambaia, Rio de Janeiro, Brasil
The acrocerids (small headed-flies) form a small group of flies, which are difficult to find and observe, and their larvae are heteromorphic parasitoids of many families of spiders and their imagoes show a great deal of morphological variation.
Ein seltener Parasitoid der Wolfspinne Pardosa alacris (Araneae: Lycosidae): Ogcodes gibbosus (Diptera: Acroceridae)
The emerging of an acrocerid fly from an adult female of the wolf spider Pardosa saltans was observed near Karlsruhe, Germany, and supports previous results suggesting that ac rocerids infect the spider's body, and not the egg sacs.
