Home of the Database of Insects and their Food Plants Family   Eriococcidae Sub Family   Description   Felt scales or eriococcids Background to Family   A greater proportion of indigenous species compared to other families in the Coccoidea, with relatively few glasshouse pests. Perhaps due to their native status, the members are more specialised than other scales recorded in Britain. Felt scales tend to occur on either on grasses, perennial plants, trees or woody shrubs.     No. taxa in DBIF   21 No. interactions   98 % interactions with British data   see notes No. records   143 % taxa with British data   see notes Notes   The Coccoidea, or scale insects, are highly adapted, sedentary feeders on mostly Angiosperm hosts. Females have neither eyes or wings, and legs and antennae are reduced or absent. The first instar 'crawler' is the dispersive stage, as is the short-lived, winged male. Females usually reproduce parthenogenetically. Most records in the database are derived from the slide collection of The Natural History Museum. ; Geographical sources of the records refer to both British and foreign regions. They indicate where the scale was recorded and where the host plant originated. Many, if not most, species will be unestablished in the wild in Great Britain.; Notes on Sources   Most recent source   1985 Below is a list of all sources for this family / sub-family contained within DBIF.
