Project 2 - Taxonomy of Mayflies and Aquatic Invertebrates2.2: Systematics, Biogeography and Ecology of Australian Aquatic Moths (Lepidoptera: Crambidae: Acentropinae)
Challenges
The Moth subfamily Acentropinae (Nymphulinae), of the family Crambidae (Pyralidae), is unique amongst the lepidopterans, as it is the only subfamily of moths, in that the larval stages are fully aquatic. Over 800 species are known from the warmer tropical and temperate regions of the world. Over 40 Australian species have been described based on adults and some 30 morphological larval taxa have been recognized. However, association between the adults and larvae are rare and consequently limit the value of this group in biological monitoring. There are also significant problems in the higher taxonomy of these groups and the the larval stages may enable some clarification of relationships which are unclear in the adults.
Seeking solutions
The objectives are:
- Undertake a systematic revision of the subfamily Acentropinae in Australia.
- Produce keys to the adults and larvae.
- Investigate the phylogeny and biogeography of Australasian Acentropinae.
- Provide biological and ecological information on the adult and larval stages.
Approaches
Contemporary DNA barcoding approaches and traditional morphological methods will be combined to associate different life stages and to enable recognition of distinct species. These will be described and published in recognized journals.
Collaboration
Tools for Decision Makers
Journal papers, web-based guides and keys, field guides.
