Thysanoptera (Thrips)

Using their tube mouthparts thrips pierce leaves and exude digestive enzymes.  When the plant material is partially digested it is pumped back into the thrip.  They may accumulate in large numbers on foliage.  when present their narrow wings have fringes.  Many species have been found to have a world-wide distribution.  This is likely to be due to their easy distribution by wind and by trade.

Suborder Terebrantia
