Key to Thrips. Thrips are tiny insects so the key is based on minute structures that must be examined under the compound microscope.
||The Royal Entomological Society of London (RES)
||Vol 1, part 11
||Covers all UK species known at the time. The main omission is Frankliniella occidentalis (Western Flower Thrips) which arrived in Britain after the key was published.
||Line drawings accompany the text.
||Under a Compound Microscope.
||Collected into 60% alcohol (with a little glycerol and acetic acid), macerated in cold 5% NaOH, dehydrated through alcohols, cleared (eg Clove Oil) and mounted in Canada Balsam. Quick and dirty preps can be made in Hoyers or Berlese mountant when a permanent preparation is not required.
||Often easier than you might expect.
