Predatory Encounters of Yllenus Arenarius (Araneae, Salticidae) with Flies (Diptera)

Abstract

<jats:p>Predatory behaviour of Yllenus arenarius hunting flies (Diptera) was studied. The general spider’s approach and capture was typical for salticids hunting prey that has high ability to escape. Two modes of approach in close proximity of prey were observed. One was typical for the majority of predatory encounters where the spider’s velocity was significantly reduced with decreasing distance to prey. Stalk and movement masking were typical for this type of approach. Second mode occurred sporadically and was characterized by a high spider’s velocity that was not reduced in the vicinity of the prey.</jats:p>

Behavioural responses and feeding preference of Aellurilus Logunovi Azarkina, 2004 (Araneae: Salticidae) to prey in a controlled environment

“…In arachnids, distinct locomotory patterns are involved which include climbing, jumping, leaping, crawling, rolling, diving and gliding (Wolff, 2021). Most Salticids are likely polyphagous predators who prefer to prey on soft-bodied and convenient to handle arthropods (Bartos, 2004;Guseinov, 2005;Huseynov, 2006). The jumping spiders of Pakistan have the least studies family than adjacent countries Iran, China and India (Ali et al, 2018;Ali, 2021;Azarkina, 2004;Azarkina, 2019;Bauer & Freudenschuss, 2015;Caleb et al, 2019;Caleb et al, 2022;Dyal, 1935;Kadam et al, 2021;Li, 2020;Logunov 2021a;c;Prószyński & Żochowska, 1981;Tripathi et al, 2021].…”
