Encyclopedia
Stigmella nubimontana is a moth
of the Nepticulidae
family. It is found in the cloud forest of the high Andes in Ecuador
.
The wingspan
is 5.2-5.3 mm for males. Adults have been found from February to early March.
The larvae feed on Rubus
species. The mine
the leaves of their host plant. The mine is usually located between two leaf veins. It consists of a compact gallery which resembles an elongated blotch. The start of the mine is slender and filled with dark brown frass
. Later, the mine widens considerably and the frass is deposited in a broad but compact central line with clear margins. The final part of the mine is very broad, sometimes even a blotch. Here, the granulated dark brown frass is deposited irregularly or into a slender central line. The final part of the mine usually covers the beginning of the mine.

Frass
Frass is the fine powdery material phytophagous insects pass as waste after digesting plant parts. It causes plants to excrete chitinase due to high chitin levels, it is a natural bloom stimulant, and has high nutrient levels. Frass is known to have abundant amoeba, beneficial bacteria, and fungi...
