Black widow spider (Latrodectus renivulatus) envenomation in children in Saudi Arabia: a case series

open access: yesToxicology Communications, 2023
Black widow spider (Latrodectus renivulatus) envenomation is a toxicological emergency affecting Middle Eastern countries. Young children may experience greater morbidity due to their small size relative to the amount of venom delivered. We describe four

A New Flaring Black Widow Candidate and Demographics of Black Widow Millisecond Pulsars in the Galactic Field [PDF]

open access: yes, 2022
We present the discovery of a new optical/X-ray source likely associated with the Fermi $\gamma$-ray source 4FGL J1408.6-2917. Its high-amplitude periodic optical variability, large spectroscopic radial velocity semi-amplitude, evidence for optical emission lines and flaring, and X-ray properties together imply the source is probably a new black widow ...

Know your foe: synanthropic spiders are deterred by semiochemicals of European fire ants

open access: yesRoyal Society Open Science, 2021
Many ants prey on spiders, suggesting that web-building spiders may avoid micro-locations near ant colonies or frequented by foraging ants. Here we tested the hypothesis that ant-derived semiochemicals deter synanthropic spiders.

Spider Web DNA: A New Spin on Noninvasive Genetics of Predator and Prey. [PDF]

open access: yesPLoS ONE, 2015
Noninvasive genetic sampling enables biomonitoring without the need to directly observe or disturb target organisms. This paper describes a novel and promising source of noninvasive spider and insect DNA from spider webs.
