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… Expand
Behavioral repertory of the weaver ant Camponotus (Myrmobrachys) senex (Hymenoptera:Formicidae)
TLDR
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. Expand
Evidences of Batesian Mimicry and Parabiosis in Ants of the Brazilian Savannah
TLDR
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)
TLDR
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. Expand
Territorial contests within and between two species of flies (Diptera: Richardiidae) in the wild
TLDR
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. Expand
Can a Common and Abundant Plant-Visiting Ant Species Serve as a Model for Nine Sympatric Ant-Mimicking Arthropod Species?
TLDR
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. Expand
Colours of war: visual signals may influence the outcome of territorial contests in the tiger damselfly, Tigriagrion aurantinigrum
TLDR
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. Expand

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, emExpand
