Mobile organisms frequently forage for patchy resources; e.g. herbivorous insects searching for host plants. The resource diffusion hypothesis predicts that insect herbivores, such as Pieris rapae butterflies, are disproportionally attracted to more isolated, or ‘diffused’, host plants. Surprisingly little is known about how this response to variation in resource density manifests itself at different spatial scales. We measured the outcome of oviposition by P. rapae butterflies foraging among… 

Resource overlap and dilution effects shape host plant use in a myrmecophilous butterfly

TLDR
The results show that plant-herbivore interactions simultaneously depend on the spatio-temporal distribution of a focal resource and on the small-scale spatial variation in the abundance of other herbivore resources.

Tri-trophic interactions and the minimal effect of larval microsite and plant attributes on parasitism of Sphenella fascigera (Diptera: Tephritidae)

TLDR
The overall rate of parasitism of S. fascigera was 25%.

The effects of squid-baiting pitfall traps for sampling wētā (Orthoptera) and other ground-dwelling forest invertebrates

TLDR
The higher catches obtained with squid-baiting, suggests this may be a useful modification to increase sampling rates, which is valuable where sampling effort is logistically constrained such as on islands or other remote study sites.

Egg laying by a butterfly on a fragmented host plant: a multi-level approach

TLDR
It is suggested that egg-placement is a process determined by factors operating at different levels: fruit, plant and host plant patch, and in well connected host plant patches (patch level).

Density‐dependence at multiple scales in experimental and natural plant populations

TLDR
In a sessile population interacting with mobile biota, the effects of density on individual fitness may vary with the way in which density is measured, which should be considered when designing and interpreting studies of spatial density-dependence.

The role of pre- and post- alighting detection mechanisms in the responses to patch size by specialist herbivores

TLDR
It is argued that basic features of foraging behaviour can explain different responses of specialist herbivores to habitat heterogeneity, and the importance of pre- and post- alighting detection in the responses of herbivore to spatial heterogeneity of the habitat is discussed.

Density effects at multiple scales in an experimental plant population

TLDR
Plant population patterns may reflect density effects interacting at different characteristic scales, and generalizations about density-dependence in spatially structured populations may be misleading if they fail to recognize that density is scale-dependent.

Patterns of herbivore incidence on experimental arrays and field populations of ragwort, Senecio jacobaea

TLDR
Six possible explanations for the diversity of density responses found amongst herbivores in this and other comparable studies are reviewed, and most are at least qualitatively consistent with the patterns observed, and thus require additional research to differentiate.

The Effect of Stand Size and Vegetational Background on the Colonization of Cruciferous Plants by Herbivorous Insects

The spatial dispersion of resources is a major factor in the population dynamics of many insects. This is especially true of herbivorous species which utilize ephemeral host plants, or which must

THE SEARCH FOR RESOURCES BY CABBAGE BUTTERFLIES (PIERIS RAPAE): ECOLOGICAL CONSEQUENCES AND ADAPTIVE SIGNIFICANCE OF MARKOVIAN MOVEMENTS IN A PATCHY ENVIRONMENT'

TLDR
A simulation of the flight behavior of ovipositing P. rapae results in the placement of more eggs on isolated hosts to demonstrate the effectiveness of egg spreading in averaging out observed variations in larval survivorship and to estimate the potential advantages accrued by egg spreading.

MOVEMENT PATTERNS AND EGG DISTRIBUTION IN CABBAGE BUTTERFLIES

TLDR
Butterfly density tends to vary inversely with host density, despite aggregative behaviour identical to that which, in predator-prey systems, leads to a direct correlation between the densities of searcher and resource.

Long-distance movement of Pieris rapae.

TLDR
This method of studying animal movement overcomes several flaws inherent in previous methods, but is restricted to distances of a few km at most.

Scale as a lurking factor: incorporating scale-dependence in experimental ecology

TLDR
It is suggested that an explicit consideration of scale could help resolve some long-standing debates when scale is turned from a lurking variable into a working variable, and four different experimental sampling designs and corresponding statistical analyses are evaluated.
