5月中旬至9月下旬，在海拔759 m、平均水深14.45 km ~ 2、最大水深6.5 m的湖泊中，用Ekman-Birge取样器采集到大型底栖摇蚊Spanutoma（Ort]locladius）ahamttsi ToKuNAGA（ToKuNAGA 1938）幼虫，沿着有刺尾类、羽尾类和管尾类。本种的出现开始于10月中旬，并于10月上旬出现。ber（YAMAGism and FuKuHara 1971）.幼虫从泥面消失（1969年Mareh的最大丰度约为5000个个体/平方米）表明它们可能在底部沉积物中挖洞。审查这个

Emergence of this species begins in mid Ocbober a[nd eonbinues to eariy Nevem. ber (YAMAGism and FuKuHARA 1971). This disappearance pf larvae (maximum abundance was about 5000 individualslm2 in Mareh, 1969) from the mud surface priar te emergence indicates that they may burrow intq the bottom sediments. To examine this
