Vespa velutina is an invasive species that was observed for the first time in France and
Europe in 2004, which rapidly threatened domestic honeybees with active predation. For the …

Anthropogenic disturbances have caused pollinator decline by affecting the abundance and
diversity of foraging plants. Anthropogenic disturbances are also thought to drive pollinator …

Females of most aculeate Hymenoptera mate only once and males are therefore under a
strong competitive pressure which is expected to favour the evolution of rapid detection of …

Studies which quantitatively analyse how aculeate parasitoids exploit their window of
opportunity to find and attack a host are scarce, despite the recognized importance of …

Nesting in dense aggregations is common in central place foragers, such as group-living
birds and insects. Both environmental heterogeneity and behavioral interactions are known …

In a coastal salt-marsh of Spain, the digger wasp Stizus continuus primarily hunted for
grasshoppers of the genus Heteracris, revealing (at least in the period of the study and in …

Individual foraging behaviour defines the use of resources by a given population and its
variation in different ways such as, for example, unpredictable interactions between taxon …

Studies on social spacing usually analyse spatial distribution using a single distribution
index, and compare this with expected values assuming random spacing. However, different …

Intuitively, larger predators in a population may be favoured in subduing, handling and
carrying to the nest a wider range of prey compared to smaller ones. In absence of any …

Research into the driving forces behind spatial arrangement of wasp nests has considered
abiotic environmental factors, but seldom investigated attraction or repulsion towards …
