Guide to New Zealand's freshwater invertebrates
Paucispinigera is one of our lesser known members of the Chironomini subfamily of chironomid midges. Like other chironomids the general body form is worm-like, but with a distinct head, and with paired prolegs under the head and at the end of the abdomen. Paucispinigera has a slender body that may be red when live (pale when preserved). The head is small and the eyes are split into two barely-separated parts, one above the other.
Paucispinigera larvae are mainly known from South Island bush-covered streams, and lakes, but there are occasional North Island records.
They are collector-gatherers feeding on fine organic matter including streambed algae.
Paucispinigera are mostly known from beech forest South Island streams (presumably with good water quality). They have tolerance values of 6 (hard bottom sites) and 7.7 (soft bottom sites).
