November
High country
Stoneflies starting to emerge, so abundance of nymphs declines from mid November. Some adult stoneflies are taken by trout but this is not particularly common. Aoteapsyche common, as well as the stone cased caddis Pycentrodes. Sporadic Deleatidium emergence common. The Deleatidium nymphs an important food source. Coloburiscus mayflies still emerging, but this should taper off towards the end of the month. Horn cased caddis becoming larger, and more abundant. Some caddis adults about, mostly at night. Onsicigaster mayfly nymphs present in non-silted rivers.
Low country
Deleatidium mayflies (both nymphs and adults), and cased caddis of all species (especially sand cased caddis) the most common food sources during the day. Caddis starting to hatch, mostly on warm still evenings. The most common caddis adults have light brown wings 14mm long with a brown body and long antennae (Hudsonema sp.). Brown beetles are very common at night near streams with grassy banks. On still warm nights they hatch in huge numbers just after dusk and a great number fall prey to trout. Chronomids (midge larvae) can be an important food source from now until February.
