The Richardiidae are acalyptrate dipterans about which very little is known. Here we describe male-male agonistic interactions and test a hypothesis of ant-mimicry in a new richardiid species in the genus Sepsisoma. Males of Sepsisoma sp. show several ritualized agonistic behaviors, with a clear escalation from simpler to more elaborate displays, which are described here in detail. We could distinguish four (not clearly discrete) behavioral stages during the escalation: Chase, Orientation, Leg… 

Behavioral repertory of the weaver ant Camponotus (Myrmobrachys) senex (Hymenoptera:Formicidae)

The behavioral repertory of Camponotus (Myrmobrachys) senex, a Neotropical weaver ant, is described and it is suggested that immobility might be an energy saving strategy in C. senex.

Evidences of Batesian Mimicry and Parabiosis in Ants of the Brazilian Savannah

The authors' observations suggest that the morphological and behavioral similarities between these species represent a Batesian mimicry relationship in which the relatively palatable Camponotus blandus mimics the unpalatable P. termitarius for predator avoidance and the pacific association between the termitophilous colonies of these species may also suggest some level of parabiotic interaction.

Territoriality and male-biased sexual size dimorphism in Argia reclusa (Odonata: Zygoptera)

Findings suggest that male territoriality may play a significant role on the evolution of sexual size dimorphism in A. reclusa, and that other factors should also be considered to explain the Evolution of SSD in damselflies, since non-territorial males are also capable of acquiring mates.

Territorial contests within and between two species of flies (Diptera: Richardiidae) in the wild

This work assessed fight frequency of both sexes of two species in the wild, and the simultaneous effects of potential fight asymmetries, sex and species, on the outcome of territorial contests in relation with resident status.

Can a Common and Abundant Plant-Visiting Ant Species Serve as a Model for Nine Sympatric Ant-Mimicking Arthropod Species?

A study of ant-mimicking arthropod diversity revealed 10 sympatric myrmecomorphs including spiders, mantids, bugs and grasshoppers, all of which were found predominantly on extrafloral nectary-bearing and homopteran harbouring plants.

Colours of war: visual signals may influence the outcome of territorial contests in the tiger damselfly, Tigriagrion aurantinigrum

This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, as to provide real-time information about the behaviour of flies in the presence of an E. coli infestation.

Etograma do escorpião amarelo Tityus serrulatus Lutz & Mello 1922 (Scorpiones: Buthidae), em cativeiro = Comparative ethogram of the yellow scorpion Tityus serrulatus Lutz & Mello 1922 (Scorpiones: Buthidae) in captivity

Embora comuns em todo o Brasil e com grande importância medico-sanitaria, os escorpioes ainda tem seu comportamento pouco estudado. Este estudo objetivou descrever o etograma de Tityus serrulatus, em



Lek Behavior as the Mating Strategy of Setellia sp. (Diptera: Richardiidae)

Correlational data support the existence of reproductive dominance hierarchies, which are based on both male vs. male and female vs. female agonistic interactions in the richardiid Setellia sp.

Effect of herbivore deterrence by ants on the fruit set of an extrafloral nectary plant, Qualea

The role of EFNs acting against herbivores is still under discussion, and plants bearing EFNs may account for up to 31% of the woody individuals and 25% in the cerrado community of Brazil (Oliveira & Oliveira-Filho 1991).

Myrmecomorphy: morphological and behavioral mimicry of ants

The influence of ants on ecological communities is well documented by their quantitative effect on populations of other organisms (66, 176) and through the variety of relationships in which they are

A new apterous micropezid fly (Diptera: Schizophora) from Western Australia

It is shown that Badisis ambulans is a Batesian mimic of a dolichoderine ant and referred provisionally to the tribe Metopochetini of the family Micropezidae.

A Physiognomic Analysis of the `Cerrado' Vegetation of Central Brasil

The vegetation of almost the whole of Central Brasil is cerrado. It occupies more than 1 5 million km2, and runs almost uninterruptedly from the southern tropic on the borders of Paraguay nearly to
