First record of the parasitoid wasp Lymeon sp. (Ichneumonidae: Pimplinae) associated with spider eggs-sac of Araneus vincibilis (Araneae: Araneidae) in Northeastern Brazil.

Brazilian journal of biology = Revista brasleira de biologia, 2020
Lymeon Förster, 1869 is a very large genus of the Cryptinae (Ichneumonidae) with predominantly Neotropical distribution where females attack small cocoons of various groups of insects and spider eggs-sac.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females

Integrative Zoology, EarlyView.
We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Phylogeography of the ‘cosmopolitan’ orb-weaver Argiope trifasciata (Araneae: Araneidae)

Biological Journal of the Linnean Society, 2020
Few spider species show truly cosmopolitan distributions. Among them is the banded garden spider Argiope trifasciata, which is reported from six continents across major climatic gradients and geographical boundaries.

Nomina dubia and faunistic issues with New Zealand spiders(Araneae) [PDF]

, 2009
Attempts to clarify the identity of obscure New Zealand spider taxa have lead to the conclusion that six species are best treated as nomina dubia [Philodromus rubrofrontus Urquhart 1891 (Philodromidae); Dictyna urquhartii Roewer 1951, (Dictynidae ...

Fluctuating asymmetry in spider‐hunting wasps as a possible indicator of stress in Brazilian Atlantic Forest landscapes Assimetria flutuante em vespas caçadoras de aranhas como possível indicador de estresse em paisagens da Mata Atlântica brasileira

Ecological Entomology, EarlyView.
Agricultural cover was positively associated with fluctuating asymmetry in Trypoxylon opacum, suggesting a possible increase in developmental instability in intensively managed landscapes. Wing size was positively related to forest cover and negatively related to agricultural cover, indicating that forested landscapes may promote larger body size ...

Using citizen science as a research prioritization tool to detect co‐occurrences of the invasive species Harmonia axyridis

Insect Conservation and Diversity, EarlyView.
We studied co‐occurrences and potential novel interactions between the invasive ladybird Harmonia axyridis and local biota (plants, arthropods and fungi) across Argentina using citizen science records. We detected co‐occurrences (mainly Asteracea and Aphididae) and previously unreported interactions (predation, parasitism, interspecific mating and ...

Quantifying How Natural History Traits Contribute to Bias in Community Science Engagement: A Case Study Using Orbweaver Spiders

Citizen Science: Theory and Practice
Online citizen science platforms can be crucial to the scientific and regulatory community, but inherent biases based on organism traits can influence the likelihood of a species being reported and accurately identified.
