It is the
resinous secretion of a kind of tiny insect known as
Laccifer lacca which belongs to the family of a scale of
insect and mealy bugs of super family “Coccoidea”.
Billions of these small insects settle on fresh and
juicy branches of certain types of trees known as lac
host trees. The main lac host trees are Palas, Ber and
Kusum. The insects settle on the branches as parasites
and go on secreting resin and wax. After a certain
period of time the insects mature and spread over other
branches directly or through artificial inoculation. On
an average three hundred thousand insects produce one
kilogram of lac resin. Sticklac is the basic raw
material and is allowed to be exported from India. It
contains about 50-60% impurity.
