HIBERNATION OF COLEOPTERA [PDF]

open access: greenThe Canadian Entomologist, 1885
The condition in which Coleoptera pass the winter is a subject on which there are in American literature but few recorded observations. That no species hibernates in the egg stage is highly probable, though in all the others it occurs—some wintering in the perfect state alone, some in the larva and the imago condition, and others as larva and pupa.Many

Seasonality and distribution of Coleoptera families (Arthropoda, Insecta) in the Cerrado of Central Brazil

open access: yesRevista Brasileira de Entomologia, 2021
Coleoptera order in Brazil presents 105 families with approximately 28,000 species. The life cycle and diversity of Coleoptera are strongly influenced by climate and vegetation. The objective of this study was to evaluate the seasonality and distribution

The first fossil Coleoptera record from the Volyn Region, Ukraine, with description of a new Glesoconomorphus (Coleoptera, Mycteridae) in syninclusion with Winterschmidtiidae (Acari) and a key to species

open access: yesZooKeys, 2021
Glesoconomorphusekaterinaesp. nov. (Coleoptera, Mycteridae), representing the first ever fossil species of Coleoptera from the Volyn Region of Ukraine and the first mycterid from late Eocene Rovno amber, is described and illustrated.

Coleoptera of Canada [PDF]

open access: yesZooKeys, 2019
The beetle fauna of Canada was assessed, including estimates of yet unreported diversity using information from taxonomists and COI sequence clusters in a BOLD (Barcode of Life Datasystems) COI dataset comprising over 77,000 Canadian records. To date, 8302 species of Coleoptera have been recorded in Canada, a 23% increase from the first assessment in ...

Whirligig Beetles as Corralled Active Brownian Particles [PDF]

open access: yesJ. R. Soc. Interface, 2021, 2021
We study the collective dynamics of groups of whirligig beetles Dineutus discolor (Coleoptera: Gyrinidae) swimming freely on the surface of water. We extract individual trajectories for each beetle, including positions and orientations, and use this to discover (i) a density dependent speed scaling like $v\sim\rho^{-\nu}$ with $\nu\approx0.4$ over two ...

The diversity and evolution of odorant receptors in beetles (Coleoptera)

open access: yesInsect molecular biology (Print), 2020
The insect odorant receptors (ORs) are amongst the largest gene families in insect genomes and the primary means by which insects recognize volatile compounds. The evolution of ORs is thus instrumental in explaining the chemical ecology of insects and as

The Bostrichidae of the Maltese Islands (Coleoptera) [PDF]

open access: yes, 2015
The Bostrichidae of the Maltese Islands are reviewed. Ten species are recorded with certainty from this Archipelago, of which 6 namely, Trogoxylon impressum (Comolli, 1837), Amphicerus bimaculatus (A.G.

Henoticonus bouchardi Grouvelle transferred to Trogocryptoides Champion (Coleoptera: Salpingidae) [PDF]

open access: yes, 2013
During a revision of the genus Pharaxonotha Reitter, 1875 (Coleoptera: Erotylidae) the study of the type of Henoticonus bouchardi Grouvelle, 1919 (Coleoptera: Erotylidae), considered to belong in Pharaxonotha, was found to be misplaced.

Evolutionary history of Coleoptera revealed by extensive sampling of genes and species

open access: yesNature Communications, 2018
Beetles (Coleoptera) are the most diverse and species-rich group of insects, and a robust, time-calibrated phylogeny is fundamental to understanding macroevolutionary processes that underlie their diversity.
