Un pulgón que se alimenta de piedra.
April Fools 2016: Petrophaga lorioti
Have you ever seen rocks or stone buildings peppered with numerous holes? You may have assumed these were the result of natural erosion, but many cases are in fact caused by a widespread yet rarely-seen animal.

These holes are often the work of the stone louse (Petrophaga lorioti), a shy insect with chisel-like mandibles which chews its way through solid rock in a manner convergently similar to the gnawing of rodents. It feeds primarily on organic “biofilm” on stone surfaces, but also appears to derive some nutrition from the rock itself thanks to symbiotic lithotrophic microbes in its gut.
Originally native to Germany (where it is known as the “steinlaus”), it has spread across the globe in association with human settlements, and can be a particularly destructive pest in urban settings. Although only about 2.5cm long (1″), individual specimens have been observed to be capable of processing up to 28kg of stone (62lbs) in a single day.
Trace fossils dating back to the Cretaceous have been tentatively identified as stone louse feeding marks, suggesting the modern species may in fact be the last remnant of a lineage of “living fossils”.

...possierlich ;-)
Auch wenn ich wahnsinnige Angst vor Spinnen habe, finde ich das einfach klasse. Schon allein deswegen: "'Die Spinnen der Gattung Otacilia haben keine Nudeln im Gesicht, ähneln weder einem Mops noch einer Steinlaus und sind überhaupt eher unscheinbare Tiere', heißt es in der Senckenberg-Mitteilung." Großartig!
Eine unvergessene Persiflage auf Bernhard Grzimek. Die Steinlaus zerstört, was ihr in den Weg gerät!
