New extreme morphologies as exemplified by 100 million-year-old lacewing larvae [PDF]

open access: yes, 2021
Larvae of the group Holometabola (beetles, wasps, flies, moths and others) differ significantly in their morphology from their corresponding adults. In most larvae, appendages and other structures protruding from the body (antennae, palps, legs, trunk ...

The Paragenital Organ of Stylopidae (Insecta: Strepsiptera) and the Functional Incorporation of the Secondary Larval Exuvia

open access: yesJournal of Morphology, Volume 286, Issue 9, September 2025.
In the insect order Strepsiptera, we identified a paragenital organ in the family Stylopidae that serves as a secondary genital organ for traumatic insemination. We show that the cuticle at the penetration sites is thickened in all species studied, relative to control sites.

Novel regulation of the homeotic gene Scr associated with a crustacean leg-to-maxilliped appendage transformation. [PDF]

open access: yes, 2014
Homeotic genes are known to be involved in patterning morphological structures along the antero-posterior axis of insects and vertebrates. Because of their important roles in development, changes in the function and expression patterns of homeotic genes ...

Consumer or Decomposer? Behavioral and Morphological Diagnosis of White Grubs

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
Determining the ecological role of insect larvae is crucial for pest control and resource utilization, relying on effective behavioral or morphological identification traits. This study uses an improved six‐armed olfactometer to analyze the feeding habits of two sympatric white grubs and the correlated morphological traits, including the sensory ...

Evolutionary implications of a deep‐time perspective on insect pollination

open access: yesBiological Reviews, Volume 100, Issue 4, Page 1452-1466, August 2025.
ABSTRACT Plant pollination by insects represents one of the most transformative and iconic ecological relationships in the natural world. Despite tens of thousands of papers, as well as numerous books, on pollination biology published over the past 200 years, most studies focused on the fossil record of pollinating insects have only been published in ...

The insect head rewound: Clarifications to the groundplan of Hexapoda (Pancrustacea) [PDF]

open access: yes
The organization of the hexapod head remains a cornerstone problem in arthropod systematics, central to segmental homology, character definition, higher-level phylogeny, and functional and evolutionary morphology.

Niche Differentiation of Three Terrestrial Isopod Species Based on DNA Metabarcoding

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Species coexistence is a hot topic in ecology, with niche differentiation playing a key role in reducing interspecific competition. This study investigates the dietary habits and niche differentiation of three terrestrial isopod species (Armadillidium vulgare, Sphaeroma raffaelei, and Trachelipus semiproiectus) using DNA metabarcoding technology.

Gastritis over Gastrisus Sharp (Coleoptera: Staphylinidae: Xanthopygina): Resolving a major taxonomic impediment with phylogenomics

open access: yesSystematic Entomology, Volume 50, Issue 3, Page 449-468, July 2025.
Comprehensive phylogeny of Xanthopygina rove beetles (Coleoptera: Staphylinidae), including 30 of 33 genera, was generated by anchored hybrid enrichment of 1229 nuclear, protein‐encoding loci. We resolved nine major clades within Xanthopygina, including the new Leptodiastemus group, and successfully delineated a monophyletic concept of Gastrisus ...

Embryonic Development of Appasus japonicus Vuillefroy, With Special Reference to Mouthparts Formation (Insecta: Heteroptera, Belostomatidae)

open access: yesJournal of Morphology, Volume 286, Issue 5, May 2025.
In this study, we provide a detailed description of the embryonic development of Appasus japonicus, focusing on the formation of its specialized mouthparts. We identify homologies between the maxillary plate and maxillary palp and most parts of the stylet‐like mandibles and maxillae are housed within the labial palp.

Interactions between host plant quality and non‐consumptive predator effects on oviposition and larval behaviour of Plutella xylostella (Lepidoptera: Plutellidae)

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 2, Page 148-159, May 2025.
Abstract The presence of predators can induce non‐consumptive effects on prey that result in subsequent changes to prey behaviour and defence. We investigate the interaction between top‐down non‐consumptive effects of various stages of the predator Coccinella septempunctata L.(Coleoptera: Coccinellidae) (larvae and adult) and bottom‐up effects of host ...
