Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]

open access: yes, 2011
Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here

Addressing Gaps in Butterfly Population Monitoring to Catalyze Global Insect Conservation

open access: yesConservation Letters, Volume 19, Issue 2, March/April 2026.
ABSTRACT The conservation community sorely lacks a global indicator of change in insect populations. Given widespread insect declines, addressing this gap is key for conservation and policy targets. We suggest that butterfly monitoring programs can serve as the foundation for an effective global network of insect monitoring.

Speed or sperm: A potential trade-off between development and reproduction in the butterfly, Bicyclus anynana (Lepidoptera: Nymphalidae)

open access: yesEuropean Journal of Entomology, 2010
Life-history theory predicts trade-offs between resources invested in reproduction and other fitness-related traits. To date, most studies have focused on potential reproductive trade-offs in females.

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

open access: yes, 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.

Geographic Variation in the Diet of Red Knot (Calidris canutus) Chicks Reflects Local Prey Communities

open access: yesJournal of Biogeography, Volume 53, Issue 3, March 2026.
ABSTRACT Aim To describe and compare the diets of an Arctic‐breeding shorebird, the Red Knot (Calidris canutus), across three geographically distinct breeding sites. We aimed to document the dietary patterns and identify key prey groups that characterise each population's foraging ecology.

The complete mitochondrial genome of the Jackson’s leaf butterfly Mallika jacksoni (Insecta: Lepidoptera: Nymphalidae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The Jackson’s leaf butterfly Mallika jacksoni (Sharpe 1896), is a leaf-mimicking species from tropical East Africa. Genome skimming by Illumina sequencing permitted the assembly of the complete circular M. jacksoni 15,183 bp mitogenome. It consists of 79.

Temporal variation in abundance and diversity of butterflies in Bornean rain forests: opposite impacts of logging recorded in different seasons [PDF]

open access: yes, 2005
We used traps baited with fruit to examine how the temporal variation of butterflies within primary forest in Sabah, Borneo differed between species. In addition, we compared patterns of temporal variation in primary and selectively logged forest, and we

Egg Adhesion of the Codling Moth Cydia pomonella L. (Lepidoptera, Tortricidae) to Synthetic Substrates

open access: yesJournal of Applied Entomology, Volume 150, Issue 2, Page 243-253, March 2026.
ABSTRACT Previous studies on Cydia pomonella eggs have demonstrated reliable egg adhesion to the leaves and fruits of various apple cultivars. In contrast to biological substrates, this study is focused on standardised synthetic substrates to measure egg pull‐off forces and determine adhesive strength, allowing for an unbiased comparison with other ...

Mobility in a Wyoming Population of Speyeria Atlantis as Determined by Tagging (Lepidoptera: Nymphalidae) [PDF]

open access: yes, 2017
Excerpt: In my study of Speyeria distribution (Moeck, 1957; Grey & Moeck, 1962; Grey, Moeck & Evans, 1963) it was found desirable to determine the degree of mobility of the individuals in a population of Speyeria atlantis (Edwards).
