All social insects defend their colony from predators, parasites, and pathogens. In Oster and
Wilson's classic work, they posed one of the key paradoxes about defense in social insects …

As social insects, ants represent extremely interaction-rich biological systems shaped by
tightly integrated social structures and constant mutual exchange with a multitude of internal …

Ants show remarkable ecological and evolutionary success due to their social life history
and division of labour among colony members. In some lineages, the worker force became …

A main challenge in the analysis of division of labor in insect societies characterized by
worker polymorphism has been identifying the number of physical castes and determining …

Genital morphology, a cornerstone in taxonomy that predates Linnaeus's Systema Naturae,
is vital for species delimitation. However, the widely accepted paradigm that genitalia are …

The division of labor into sterile and reproductive castes in social insects is often reflected in
marked morphological differences, which might have played an important role in the …

Food processing can exert significant evolutionary pressures on the morphological evolution
of animal appendages. The ant genus Pheidole displays a remarkable degree of …

Conventional methods such as microscopy have been used to diagnose parasitic diseases
and medical conditions related to arthropods for many years. Some techniques are …

Many species have evolved alternate phenotypes, thus enabling individuals to conditionally
produce phenotypes that are favorable for reproductive success. Examples of this …

Simple Summary Determination of species in the ant genus Odontomachus, which is a
venomous group of ants, may require the use of highly trained entomologists. In Thailand …
