We have been field observers of tropical insects on four continents and, since 1978, intense observers of caterpillars, their parasites, and their associates in the 1,260 km² of dry, cloud, and rain forests of Área de Conservación Guanacaste (ACG) in northwestern Costa Rica. ACG’s natural ecosystem restoration began with its national park designation in 1971. As human biomonitors, or “insectometers,” we see that ACG’s insect species richness and density have gradually declined since the late 1970s, and more intensely since about 2005. The overarching perturbation is climate change. It has caused increasing ambient temperatures for all ecosystems; more erratic seasonal cues; reduced, erratic, and asynchronous rainfall; heated air masses sliding up the volcanoes and burning off the cloud forest; and dwindling biodiversity in all ACG terrestrial ecosystems. What then is the next step as climate change descends on ACG’s many small-scale successes in sustainable biodevelopment? Be kind to the survivors by stimulating and facilitating their owner societies to value them as legitimate members of a green sustainable nation. Encourage national bioliteracy, BioAlfa.

我们一直是四大洲热带昆虫的野外观察员，并且自1978年以来，我们就在1,260 km ^2内对毛毛虫，它们的寄生虫及其伴生进行了深入观察。哥斯达黎加西北部的ÁreadeConservaciónGuanacaste（ACG）的干旱，云雾和雨林。ACG的自然生态系统恢复始于1971年的国家公园指定。作为人类生物监测仪或“昆虫测量仪”，我们看到ACG的昆虫物种丰富度和密度自1970年代后期以来逐渐下降，并且自2005年左右以来更加剧烈。气候变化。它导致所有生态系统的环境温度升高；季节性线索更加不稳定；减少，不稳定和异步降雨；热气团从火山上滑下来，烧毁了云雾森林；以及所有ACG陆地生态系统中生物多样性的减少。随着气候变化归因于ACG在可持续生物发展方面取得的许多小规模成功，下一步该怎么办？通过激励和促进其主人社会将其视为绿色可持续发展国家的合法成员，对幸存者保持友善。鼓励国家生物素养，BioAlfa。
