The secret electrostatic world of insects
Insects like bees and spiders use static electricity for navigation, predation, and pollination, enhancing survival and ecological interactions, with ongoing research exploring the evolutionary implications of these abilities.

Insects, particularly bees, spiders, and moths, utilize static electricity in various ways that significantly impact their survival and ecological interactions. Research has shown that bees can detect electric fields from flowers, allowing them to collect pollen without direct contact. This phenomenon, termed aerial electroreception, suggests that static electricity plays a crucial role in the relationships between pollinators and plants. Studies indicate that spiders can attract prey using charged webs, while ticks and other parasites may exploit electric fields to find hosts. The research, led by scientists like Daniel Robert and Víctor Ortega-Jiménez, highlights how these small creatures experience a world rich in electrostatic interactions, which are largely imperceptible to larger animals, including humans. The findings raise questions about the evolutionary significance of these abilities, suggesting that static electricity may have shaped behaviors and adaptations in these species. As scientists continue to explore this field, they aim to uncover the extent to which electrostatics influence animal behavior and ecological dynamics.

16 commentsVery cool article. For example: butterflies accumulate a positive charge when beating their wings, which causes pollen to jump through the air toward them when they land on flowers.

Interesting that ticks literally get pulled like a magnet towards their targets due to electrostatic forces.
This article has multiple videos of it:

It's arguably kind of weird that this is just being noticed now. I suppose possibly modern camera equipment helps, for purposes of actually _seeing_ it happen...
This is all so fascinating!
I did some amateur research on spider ballooning many years ago and I believe part of the lift comes from rising air dragging along the silk thread. From my calculations, it wasn't enough to lift the spider on its own, but it might allow the spider to fall slower than the convective air currents were rising.

There are other electromagnetic type things too, like use of light (camouflage, bioluminescence, eyes) and electricity (electric eels, bioelectrical cues for stem cell differentiation).
EDIT: Also the literal electrical potential within cells: the membrane potential, that is the voltage difference between inside and outside every cell.
An interesting area!
