Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

open access: yesOikos, Volume 2026, Issue 7, July 2026.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

The central-marginal hypothesis in acridid Orthoptera: A critique of Colombo's (2012) article

open access: yesEuropean Journal of Entomology, 2013
We discuss and criticise the contention of Colombo (2012) that the central-marginal model does not apply to three species of chromosomally polymorphic acridid grasshoppers, and that chromosomal clines in these species are a consequence of temperature ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Correlation between metabolic depression and ecdysteroid peak during embryogenesis of the desert locust, Schistocerca gregaria (Orthoptera: Acrididae)

open access: yesEuropean Journal of Entomology, 2000
Respiratory metabolism of developing eggs of Schistocerca gregaria has been individually monitored by means of scanning microrespirography. The freshly oviposited eggs consumed 7 nl of O2 /min./egg (50 µl O2/g/h) while the pharate 1st instar larvae ...

Diversity of Resilin Incidence in the Insect Leg

open access: yesJournal of Morphology, Volume 287, Issue 6, June 2026.
Resilin incidences in the insect cuticle are commonly detected by fluorescence microscopy using the property of Resilin protein matrices to emit blue light after excitation with UV light. This indirect method produces significant background signal.
