The larvae of Chironomidae are very important due to their density and role in aquatic food webs. Goeldichironomus holoprasinus Goeldi is one of the most abundant species of Chironomidae in man-made and natural systems, being widely used in water quality assessments. Because of its tolerance to stressing environmental factors, many studies have investigated the effects of stressors on G. holoprasinus anatomy and bionomic attributes. The main aim of this work was to describe G. holoprasinus life cycle attributes in laboratory conditions. The cephalic capsule growth among instars was 1.64 in average (Dyar proportion), whereas the total size growth was continuous. The average room temperature registered was 26 degrees C (18-33 degrees C). In this conditions the D value (time from oviposition to first imago emergence) was 13 days, whereas the minimum G value (interval from the oviposition to the first progeny of the next generation) was 16 days. The emergence lasted four days, which determined that average G of 18 days. Thus, at registered temperatures G. holoprasinus has a short life cycle.
摇蚊科幼虫因其密度以及在水生食物网中的作用而非常重要。戈氏全绿摇蚊是人造和自然系统中最常见的摇蚊科物种之一，被广泛用于水质评估。由于其对压力环境因素具有耐受性，许多研究调查了应激源对戈氏全绿摇蚊解剖结构和生物学特性的影响。这项工作的主要目的是描述实验室条件下戈氏全绿摇蚊的生命周期特性。龄期之间头部胶囊的生长平均为1.64（戴尔比例），而总体大小的生长是连续的。记录的平均室温为26摄氏度（18 - 33摄氏度）。在此条件下，D值（从产卵到第一只成虫出现的时间）为13天，而最小G值（从产卵到下一代的第一只后代的间隔）为16天。羽化持续了四天，这使得平均G值为18天。因此，在记录的温度下，戈氏全绿摇蚊具有较短的生命周期。
