In an effort to understand why some groups of insects, especially beetles, are much more diverse than others, analyses were carried out on the role of morphological, life-history, and ecological factors on the species richness of various orders, as q

Nearly half of the “Schemata” (engravings) in Robert Hooke’s seminal work of science Micrographia (1665) show either entire invertebrates or their body parts, and a similar proportion of the “Observations” (descriptions and conjectures) eit

Parasitoidism of ants by flies is known only for Phoridae and Tachinidae. We report the first record of a hoverfly (Syrphidae, Microdontinae, Hypselosyrphus) acting as a true primary parasitoid of ants. Previously, larvae of Microdontinae were known

The illustrations in Robert Hooke's epoch-making publication Micrographia became the standard reference work for depicting microscopic phenomena. Of the book's 38 engravings (the “Schemata”), 14 illustrate insects or their body parts, and of its

An important assumption in insect parasitoid life-history theory is that, within parasitoid complexes (species assemblages associated with particular hosts), members attacking young host stages are more fecund than members targeting older ones. This

Understanding the factors that constrain the reproductive success of animals and their demographics requires detailed insight into the processes of resource acquisition and allocation in relation to habitat richness. Parasitoid wasp females are valua

In attempting to explain the marked interspecific variation evident in many components of life-history in parasitoid wasps, biologists have sought to identify general predictors of suites of ‘important’ life-history traits. Two predictors current

One of the key predictions of general life-history theory is that reproduction incurs a survival cost. Although there is a convincing body of evidence to support this prediction at the intraspecific level in insects, evidence at the interspecific lev

A prediction arising from several evolutionary diet breadth models is that, in insect herbivores whose adults practise adaptive host plant selection based on larval performance, female adult lifespan should be negatively correlated with larval diet b

1. Insects vary considerably between and within orders, and even within the same genus, in the degree to which the female's lifetime potential egg complement is mature when she emerges as an adult. 2. The 'ovigeny index' (OI) - the number of eggs fem
