"Tiny Pseudoscorpion Hitches a Ride on Scorpion"

Researchers from The Hebrew University of Jerusalem have documented the first observation of phoresy, a phenomenon where pseudoscorpions attach themselves to hosts for dispersal, involving a myrmecophile pseudoscorpion on a myrmecophile scorpion in Israel. The study, published in Arachnologische Mitteilungen: Arachnology Letters, focuses on the Nannowithius pseudoscorpions observed on the Birulatus scorpion, marking the first recorded instance of pseudoscorpions engaging in phoresy on a scorpion host. This observation sheds light on the intricate world of symbiotic relationships within the ant nest ecosystem and raises questions about dispersion cues and the co-evolutionary relationship between pseudoscorpions and scorpions.

Nematodes Hitchhike on Bumblebees Using Electric Fields

Japanese scientists have discovered that nematodes (C. elegans) use electric fields to leap from the bottom of Petri dishes to the lid and even onto bumblebees. The worms rely on a type of phoresy to achieve range and use a behavior known as "nictation" to attach to passing larger animals. Unlike snails and bugs, flying insects like bumblebees naturally accumulate charge during flight, producing an electric field. The researchers found that the worms only lept to the other electrode when the charge was applied and moved at an average speed of 0.86 meters per second.
