Here, we tested the adhesiveness of viscid silk on the superhydrophobic lotus leaf, an extreme case of a hydrophobic surface, to explore whether hydrophobic cuticles can help insects evade webs. We compared adhesion of viscid silk on three substrates: natural lotus leaves (superhydrophobic due to waxes and microtopography), lotus leaves treated with oxygen plasma (hydrophilic but maintaining microtopography), and smooth hydrophilic glass. We found that viscid silk adheres better to the superhydrophobic lotus leaves than to other surfaces, but that adhesion was always higher on the lotus leaves, regardless of surface energy. These findings demonstrate that viscid silk is resilient to a wide range of surface hydrophobicity and leverages microtopography to increase adhesion, both of which are vital for generalist predators like orb-weaving spiders and may inspire the development of tunable adhesives with multifunctional applications in biomedical, industrial, and robotic fields.</p>","PeriodicalId":9216,"journal":{"name":"Biology Open","volume":"14 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12079571/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143976998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A variety of bioluminescent organisms inhabit soil environments, even in areas where light penetration is minimal.

Springtails (Collembola) are representative soil animals, and we recently identified Lobella sauteri (Neanuridae) as a bioluminescent species. L. sauteri can be maintained over multiple generations under laboratory conditions on a single food source, the plasmodium Fuligo septica, with a generation time of approximately 3 months. Bioluminescence was observed in all developmental stages of L. sauteri in laboratory-raised populations. The light emission exhibited periodic changes and increased before ecdysis, coinciding with the whitening of its tubercles. The bioluminescent reaction in vitro requires a small molecular (luciferin) fraction, an enzyme (luciferase) fraction, adenosine triphosphate (ATP), and Mg2+. Comparative transcriptomic and biochemical analyses suggest that L. sauteri employs a novel endogenous bioluminescent molecular mechanism.

To test whether the late arrival of water waves - which travel more slowly than sound - could explain crocodiles' preference for the source of water waves, we controlled the relative timing of stimulus arrival within a time window of a few seconds. Our results reveal that crocodiles preferentially move towards the source of the water waves, whether they arrive after, at the same time as, or before the sound. This suggests that the temporal integration of information from different sensory channels can occur within a certain time window, where the behavioural decision-making remains independent of the arrival order of stimuli.
