在1992年和1993年夏季分层期间，丹麦埃斯罗姆湖的炭疽摇蚊的生长和糖原含量进行了研究。同时，实验研究了缺氧对糖原利用和存活的影响。1992年，种群由几乎完全发育的4龄幼虫组成，1993年由2龄和3龄幼虫组成。生长速率和糖原含量随缺氧程度的增加而变化。在第1阶段的层积干重和糖原含量增加（2日和3日龄）或几乎是恒定的（4日龄），但在随后的第2阶段显着下降。这种从生长到退化的变化以及内源性糖原储备的利用与微囊层厚度的变化相关（
Growth and glycogen content of Chironomus anthracinus in Lake Esrom, Denmark was examined during summer stratification in 1992 and 1993. Simultaneously, effects of oxygen deficiency on glycogen utilization and survival were experimentally studied. The population consisted of almost fullgrown 4th instar larvae in 1992 and 2nd and 3rd instar larvae in 1993. Growth rate and glycogen content changed as hypolimnetic oxygen deficiency increased. During a 1st phase of stratification dry weight and glycogen content increased (2nd and 3rd instars) or was almost constant (4th instar) but decreased significantly during the following 2nd phase. This change from growth to degrowth and utilization of endogenous glycogen reserves correlated with a change in the thickness of the microxic layer (
