Chopard's Mountain Bush-cricket

Chopard's Mountain Bush-Cricket (Antaxius chopardi) is a bush-cricket (katydid) in the family Tettigoniidae, endemic to mountain ranges in the western Mediterranean region, likely including the Pyrenees and associated mountain systems of southern France and northern Spain. Bush-crickets of the genus Antaxius are large, robust tettigoniids characterised by females bearing a pronounced ovipositor for egg insertion into soil or plant tissue, and males producing species-specific stridulatory songs by rubbing modified wing structures. Despite the name mountain bush-cricket, members of this genus inhabit a range of grass-shrub-dominated montane habitats including rocky slopes, mountain meadows, and scrubland edges. They are primarily herbivorous, feeding on grasses, herbs, and low shrubs, though they may supplement their diet with small invertebrates. Stridulation songs are important for species identification in this cryptically coloured group, as multiple Antaxius species may co-occur in the same mountain range. The IUCN classifies this species as Least Concern, with populations found across suitable montane habitats within its range. The species is named after Lucien Chopard, recognising his extensive contributions to the study of European orthopteran (crickets and grasshoppers) biodiversity. Climate change-driven shifts in vegetation zones may pose future threats to montane endemic invertebrates.

Common Script Lichen

<em>Graphis scripta</em>, the common script lichen, is a crustose lichen in the family Graphidaceae, order Graphidales, with a cosmopolitan distribution spanning Asia, Europe, North America, and South America. This species grows as a flat, tightly attached crust on the smooth bark of deciduous trees in humid, shaded woodland habitats, where it is often among the most frequently encountered bark lichens. The distinctive feature of <em>Graphis scripta</em> is its elongated, script-like apothecia — black, slit-like fruiting bodies that resemble ancient writing and give the species its common name. As a lichen, it represents a stable mutualistic association between a fungal partner (mycobiont) and photosynthetic algal or cyanobacterial partners (photobionts). The species is listed as Least Concern by the IUCN, reflecting its wide distribution and tolerance across a range of forested habitats. It is considered sensitive to air pollution, particularly sulfur dioxide, making it a useful bioindicator of air quality. Biological traits for this species remain poorly documented in the scientific literature, including data on growth rates, lifespan, and detailed ecological interactions beyond its known substrate preferences.
