Dilta agg.


    Dilta are a genus of primitive wingless invertebrates with long antennae. They are slender with dull, often mottled, colouring and jump when disturbed. Although difficult to identify to species level, they can be placed in a genus by examining the arrangement of the ocelli (eyespots). Bristletails are difficult to identify to species level and precise identification requires examination of microscopic features. Unfortunately identification can only be performed on adult males and many populations are all female (parthenogenetic) so cannot be identified beyond genus level. On NatureSpot we group them together as Dilta agg.
