In this study, the diversity of adult Trichoptera varied widely over the months. A total of 762
male individuals were caught belonging to 72 species of 14 families (Table 1). The distribution of
families (Figure 3) and the flight graphics of the 10 most common species in terms of individuals, and
time of collection of 72 species, were based on the monthly count of specimens in the traps (Figure 4).
Adult Trichoptera were present at all times of the year in a stream. The highest abundance of
adult caddisflies were collected in the dry season (February to April) while the lowest was recorded in the
wet and cold season (June to October) (Table 1).
