古生代-中生代过渡的特点是中生代最大规模的灭绝。然而，一个令人印象深刻的适应辐射的食草性昆虫发生在裸子植物为主的植物群不早于在中晚三叠世，准同期与世界各地的类似事件，所有这些表现出平行的广义和大多数专业化的植物上的昆虫植食性的扩张，表现为昆虫对各种植物器官和组织的损害。来自Monte Agnello的植物群是独特的，因为它保存在亚气沉积的火山碎屑层中，具有异常保存的细节。因此，准原地组合提供了洞察环境干扰，火山活动造成的，以及它们如何深刻地影响了结构和组成的食草动物模式。这些不同的中三叠世生物群提供了广泛的证据，昆虫草食动物殖民化，导致特定的和复杂的草食动物模式，涉及20个独特的损害类型（DT）的频率和多样性。这些DT模式表明，外部食叶者、刺吸者、潜叶者、刺蛾和产卵罪犯复杂地使用来自voltzialean针叶树的优势寄主植物的几乎所有组织类型（例如，Voltzia）、马尾、蕨类（例如，Neuropteridium，Phlebopteris，Cladophlebis和Thaopteris），种子蕨（例如，Scytophyllum）和苏铁植物（例如，Bjuvia和Nilssonia）。
The Paleozoic–Mesozoic transition is characterized by the most massive extinction of the Phanerozoic. Nevertheless, an impressive adaptive radiation of herbivorous insects occurred on gymnosperm-dominated floras not earlier than during the Middle to Late Triassic, penecontemporaneous with similar events worldwide, all which exhibit parallel expansions of generalized and mostly specialized insect herbivory on plants, expressed as insect damage on a various plant organs and tissues. The flora from Monte Agnello is distinctive, due to its preservation in subaerially deposited pyroclastic layers with exceptionally preserved details. Thus, the para-autochthonous assemblage provides insights into environmental disturbances, caused by volcanic activity, and how they profoundly affected the structure and composition of herbivory patterns. These diverse Middle Triassic biota supply extensive evidence for insect herbivore colonization, resulting in specific and complex herbivory patterns involving the frequency and diversity of 20 distinctive damage types (DTs). These DT patterns show that external foliage feeders, piercer-and-suckers, leaf miners, gallers, and oviposition culprits were intricately using almost all tissue types from the dominant host plants of voltzialean conifers (e.g., Voltzia), horsetails, ferns (e.g., Neuropteridium, Phlebopteris, Cladophlebis and Thaumatopteris), seed ferns (e.g., Scytophyllum), and cycadophytes (e.g., Bjuvia and Nilssonia).
