| Temperature-associated emergence patterns for a hydropsychid caddisfly, Hydropsyche kozhantschikovi, were studied from the Wangsuk creek in Kyonggi-do from April to June in 1999. Emerging adults were quantitatively collected by pyramidshaped emergence traps. Water temperature was hourly monitored in 1999. The emergence began at April 15 when the daily mean water temperature rose to ca. $10^{circ}C$: it rapidly increased and peaked in ca. 10 days, and continued to May 25, lasting 40 days since the starting date. The average number of emerged adults was $35.8;inds./m^2$ and their sex ratio was male (M) : female (F) = 1 : 2.04. The emergence of males was ca. 2 days earlier than that of females. Daily, the emergence was a bigeminans pattern representing the major peak (66.7%) just after dark ($19:00{sim}21:00$) and theminor peak (11.1%) just before dawn ($05:00{sim}07:00$). According to our degree dayaccumulation (DD) model, it respectively required 453.89DD (M: 440.48DD and F: 473.97 DD), 615.71DD (M: 610.18DD and F: 622.09DD), and 820.24DD (M: 828.25DD and F: 804.71DD) to begin, to reach the peak, and to finish the emergence. |
