Hepialidae continued

Here are another 6 moths from the family. Once again, positive identification is not possible and so they must remain a visual list of the moths from this location. For details see the "About" tab.

Hepialidae

This is one of the most difficult families to identify from photographs. The males often differ from the females, the males differ from each other and so do the females. There are regional differences as well. In fact the wing markings cannot really be relied on at all!

Some of the moths will be the same species with different markings because they were photographed over several years, and the changing ecology of the area may account for changing markings. The photographs were taken between 2010 and 2014, the last of the photos in May 2014 and, although it may be coincidental, this coincides with the removal of  a Eucalyptus tree, a Pink Bloodwood (Corymbia intermedia), which grew next to the house.

I believe that many of the photographs of the moths that I will put on the blog over the next few weeks are members of the Oxycanus genus, in fact I think most of them will be.
In keeping with the aims of this Blog, I will put all the Hepialidae moths that I have photographed on the Blog with numbers, and if anyone believes they can identify any of them with some certainty I would very much like to hear from you.

Urolitha bipunctifera GEOMETRIDAE

Urolitha bipunctifera GEOMETRINAE GEOMETRIDAE

 




Family:- GEOMETRIDAE
Sub Family:- GEOMETRINAE
Genus:- Urolitha
Species:- bipunctifera



That is the last of the Geometrid moths for the time being.
There are still a lot more that I have yet to identify, or have been unable to identify.

Heliocosma argyroleuca HELIOCOSMA Group

 




Family:- HELIOCOSMA Group
Sub Family:-
Genus:- Heliocosma
Species:- argyroleuca (probably)









 


Heliocosma argyroleuca is a member of the Tortricoidea superfamily. The wingspan is about 15 mm.











 Identification

 The internet sites I checked when trying to identify this moth shows there is a lot of confusion, particularly if going by wing pattern, colouring and other visual identifiers. Two of the normally reliable sites I use for identification have photos of what look like the same moth named as both Heliocosma argyroleuca and Heliocosma incongruana. This doesn't necessarily mean they are wrong, but there is a need to be careful.

The site boldsystems.org has a number of photos of each species separated into what appears to be the correct species groups, and so, for the time being, I will go with the best match from that site, which is Heliocosma argyroleuca. This also matches up with a couple of other sources, one of which I know the gentleman who photographed the moth is an entomologist.

This does bring up the subject of using the internet for identification. A number of sites are simply copying (or being given copies) of the information that appears on other sites. Contributors may also incorrectly identify a moth from another incorrect identification. The original identification may be incorrect and this is copied to the next site and so on.
The original photographer/ identifier may go back and correct the original source but the correction does not always flow on.

I try to get consensus from a number of sites and books and still end up with errors. I have seen photos that I have corrected after publication on this blog, turn up in other places uncorrected.

Thalaina selenaea  GEOMETRIDAE

Thalaina selenaea NACOPHORINI ENNOMINAE GEOMETRIDAE

These are a quite spectacular with flashes of red when they fly. They can also have a solid red stripe across the forewing.
The larval food is probably Acacia.


 Family:- GEOMETRIDAE
Sub Family:- ENNOMINAE
Genus:- Thalaina
Species:- selenaea















************************************************************************************

Syneora hemeropa BOARMIINI ENNOMINAE GEOMETRIDAE 

 


 Family:- GEOMETRIDAE
Sub Family:- ENNOMINAE
Genus:- Syneora
Species:- hemeropa





**********************************************************************************

Sterictopsis Poss argyraspis GEOMETRINAE GEOMETRIDAE

 




 Family:- GEOMETRIDAE
Sub Family:- ENNOMINAE
Genus:- Sterictopsis
Species:- argyraspis  (Possibly)

I am not certain of this species identification.
I believe the identification is correct down to genus.
