Distinguishing morphological features of Order:

  • 3 nymphal instars
  • Dorsoventally flattened head
  • 3 to 5 segmented antennae
  • Reduced compound eyes

Ecological Importance:

  • The order of phthiraptera are found on every continent and are known for disease transmission. Apart from the well known tick or lice species, phthiraptera importance is uncertain. The order is intriguing because of the host specificity in cospeciation.

Economic/agricultural/human health importance:

  • Because phthiraptera partake in cospeciation they are regularly used in theories about macroevolution. Scientist are able to study the different kinds of phylogeny showing evolution history. This history has shown the order to no longer be monophyletic but quite morphological with an extensive history; with this discovery in phthiraptera order scientist are eager to see what is possible for other taxa units. Other interest in the order are prevention related, where many veterinary scientist and clinicians are seeking methods of prevention of lethal disease transmission.
