+  "description": "Tiny sap-mouthed bug that grazes sulphur-tolerant lichens crusting the warm rocks of an active caldera floor. Heavily detoxifying gut symbionts let it ingest acidic, sulphate-laden tissue that would dissolve a normal insect mouthpart. Forms dense plates on warm bedrock at first light, dispersing into rock fractures when surface temperature climbs.",
