Eutachyptera is a monotypic moth genus in the family Lasiocampidae. The genus was erected by William Barnes and James Halliday McDunnough in 1912.[1] Its single species, Eutachyptera psidii, was first described by Sallé in 1857. It is found in Mexico.[2]
Behaviour
[edit]The caterpillars feed on the leaves of guava (Psidium sp.) and oak. They live communally in large silken nests, which can extend to 50 centimetres (20 in) or more in length.[3][4][5] They remain in the nests by day and leave at night to feed, laying a trail of pheromones to help them and their nest-mates navigate to and from feeding areas.[6]
Unusually among caterpillars, E. psidii larvae can remain active for as long as 18 days with no food, which they may have to do when their host trees lose their leaves in winter.[7]
Use of larvae and silk
[edit]The larvae are among the caterpillars traded and eaten in Mexico.[8]
The silk nests were used by the Aztecs, Mixtecs and Zapotecs to make a paper-like fabric, which was a commercial item at the time of Moctezuma.[4][5][9] Later, the Mixtec and other communities in Oaxaca extracted the silk fibres from the nests[10] and wove them into sashes. This practise had ceased by 1997.[11]

Large nests can be more than a meter long, but they average less than half that size ... most authors consider that G. psidii was the main source of silk in the commerce of the ancient Mexicans before and during the time of Moctezuma.
