The magnitude of cryptic insect diversity in one tropical rainforest

Insect Conservation and Diversity, Volume 18, Issue 6, Page 1163-1174, November 2025.
We detected 214 cryptic species out of a total of 2006 species (10.6%) examined from 22 focal insect taxa in 1500 ha tropical rainforest in Panama. The percentage of cryptic species varied greatly among assemblages (0%–19%), with half of the assemblages devoid of cryptic species and the highest proportions of cryptics in Pieridae and Formicidae ...

A molecular phylogeny of Polyommatus s. str. and Plebicula based on mitochondrial COI and nuclear ITS2 sequences (Lepidoptera: Lycaenidae)

European Journal of Entomology, 2010
The phylogenetic relationships of the subgenera Polyommatus and Plebicula, within the Palaearctic butterfly genus Polyommatus, were inferred from a combined analysis of the nuclear marker ITS2 and the barcoding section of the mitochondrial gene COI ...

Wolbachia Host Shifts and Widespread Occurrence of Reproductive Manipulation Loci in European Butterflies

Molecular Ecology, Volume 34, Issue 21, November 2025.
ABSTRACT Wolbachia is the most frequent bacterial endosymbiont of arthropods and nematodes. Although it is mostly vertically transmitted, from parent to offspring through the egg cytoplasm, horizontal transfer of Wolbachia is thought to be common over evolutionary timescales.

Host ant specificity of large blue butterflies Phengaris (Maculinea) (Lepidoptera: Lycaenidae) inhabiting humid grasslands in East-central Europe

European Journal of Entomology, 2008
Butterflies of the genus Phengaris have a highly specialised life cycle involving an obligatory relationship with Myrmica ants. A knowledge of the host ant specificity is essential for understanding the relationship between a particular Phengaris species

Three in one-multiple faunal elements within an endangered european butterfly species [PDF]

, 2015
Ice ages within Europe forced many species to retreat to refugia, of which three major biogeographic basic types can be distinguished: "Mediterranean", "Continental" and "Alpine / Arctic" species.

Integrating Population Genomics and Historical Occurrence Data to Assess the Impact of Land‐Use Changes on Centris Oil Bees in the Brazilian Cerrado

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Habitat loss and fragmentation (HLF) are among the major drivers of bee decline, yet closely related species often show contrasting responses depending on their ecological and demographic traits. The Brazilian Cerrado biodiversity hotspot experiences among the world's highest rates of HLF.

Increasing patch area, proximity of human settlement and larval food plants positively affect the occurrence and local population size of the habitat specialist butterfly Polyommatus coridon (Lepidoptera: Lycaenidae) in fragmented calcareous grasslands

European Journal of Entomology, 2011
Which factors influence the occurrence, population size and density of species in fragmented habitat patches are key questions in population and conservation ecology.

Ability of males of two theclini species (Lepidoptera: Lycaenidae) to discriminate between sexes and different types of females based on the colour of their wings

European Journal of Entomology, 2015
Many territorial species of butterfly are sexually dimorphic in their wing colours, and males of such species frequently fight each other, probably attracted by the rival's wing colour.
