 Hypertrophidae

Hypertropha possibly desumptana species HYPHERTROPHIDAE
This is one of those moths that has moved about a bit.
The original genus of Hypertropha was placed in the family Glyphipterigidae (Sedge moths), next it was transferred to Hypertropha in Copromorphidae (fruit worms), next it was placed in Hypertrophidae (twig moths), then reassigned to a sub family of Hypertrophinae in Glyphipterigidae, then moved again to Oecophoridae and finally moved (by I.F.B. Common Moths of Austrtalia P234) to a separate family Hypertrophidae.
Although most of the books and internet sites use Hypertrophidae as a family some are still placing the moths in Oecorphoridae.
Larval food is most likely Eucalyptus leaves.

Hypertropha   desumptana (Possibly)  HYPHERTROPHIDAE




Family:- HYPHERTROPHIDAE
Genus:- Hypertropha
Species:- desumptana (Possibly)






There is another genus Peritropha, which is sometimes placed in Depressariidae, which is similar, but I think Hypertropha is correct.

This weeks post is a little late because we had what could be called "a good bit of rain" during the week.
A tropical cyclone ( Debbie) crossed the coast about 1000 Km to the north of us then turned into a rain depression and headed south with heavy rainfall and a lot of local flooding.
(Search for cyclone Debbie, Australia on the internet and you will see what I mean.)
Hopefully the rain is not too late for the moths to take advantage of the rapid growth in the plants. It has been a very dry summer and this rain is quite late in the season.

Teak moths

Hyblaea ibidias HYBLAEIDAE

Although this moth is related to H. puera which causes severe damage to the teak forests through India, Indonesia and New Guinea, the Hyblaea ibidias larvae feed on Bower vine Pandorea jasminoides, (BIGNONIACEAE).
The larvae have an unpleasant habit if handled, of squirting the contents of its gut at the source of the interference. 







Family:- HYBLAEIDAE
Genus:- Hyblaea
Species:- ibidias












 The rear wings are quite spectacular.
















The last photo is a moth that has lost most of its scales and is in poor condition. This is unfortunately the state of many of the moths we are seeing. Poor rainfall coming in storms with little in between has resulted in a year with low moth numbers
and very few of the larger moths coming to light at night.

Herminiidae

This family of moths have not been well studied. They are very similar to moths from the sub family of  Hypeninae in Noctuidae, so if trying to identify moths that look similar check both families.
The larvae that have been studied live on the dead and decaying leaves on forest floor.
Note the large labial palpi particularly on the first photos.






Family:-  HERMINIIDAE
Genus:- Simplicia
Species:- armatalis














Family:- HERMINIIDAE
Genus:- Simplicia
Species:- caeneusalis















Family:- HERMINIIDAE
Genus:- Lithilaria
Species:- ossicolor













Family:- HERMINIIDAE
Genus:- Nodaria
Species:- aneliopis (possibly)

Aquatic moths

Margarosticha euprepialis ACENTROPINAE  CRAMBIDAE

 


Family:-  CRAMBIDAE
Sub Family:- ACENTROPINAE
Genus:- Margarosticha
Species:- euprepialis (probably)


Moths of the sub family ACENTROPINAE, which used to be called NYMPHULINAE, (and still is, by some sites and some books), are aquatic moths. There are believed to be some 50 species of aquatic moths in Australia.

The larvae live in the water obtaining oxygen through diffusion through the skin on the very small larvae, some capture oxygen from the surface and trap it in the hairs on their bodies, and most in Australia have sort of gills along the sides of their bodies.

The arrival of this moth is an interesting case. Our garden pond was leaking badly and needed to be repaired. In the process all the pond weed that we had died, and we replaced the plants with some bought from a pet supply shop and some from a local nursery. A couple of weeks after the pond was back in action we had this moth appear.
I am not sure if the moth is a local or brought in on the pond weed which probably came from the wholesale suppliers near the coast.

A Confusion of names
 Margarosticha euprepialis ACENTROPINAE  CRAMBIDAE
 Sub family of ACENTROPINAE was previously known as NYMPHULINAE and is still used on some sites and in older books. The name Nymphicula australis is also used for Margarosticha australis calling M. australis a synonym along with Cataclysta australis

Parapoynx diminutalis ACENTROPINAE CRAMBIDAE 

We have previously had another aquatic moth, Parapoynx diminutalis ACENTROPINAE CRAMBIDAE here, most likely breeding in our pond.


 Family:- CRAMBIDAE
Sub Family:- ACENTROPINAE
Genus:- Parapoynx
Species:- diminutalis








Hygraula nitens ACENTROPINAE CRAMBIDAE

This another aquatic moth we have had here. The hairs on the caterpillars are actually gills.

More Hepialidae

This is the last of the Hepialidae moths for the time being. Despite the difficulties with identification  they are a spectacular moth and a frequent visitor here.
I think all these moths belong to the genus Oxycanus.


HEPIALIDAE 0009 on  -3963
probably the same as
 0059 - 4057
below


HEPIALIDAE 0011 - 3965

HEPIALIDAE 0059 - 4057








HEPIALIDAE 9953 on - 4016

HEPIALIDAE 9996  - 4052

HEPIALIDAE 9996 on - 4051







The reason for the unnamed photos is refer to the post February 15th 2017.
