Monopis Moths

 Monopis chrysogramma TINEINAE TINEIDAE

The genus Monopis is quite unusual. In some of the species, the females of Monopis have an enlarged genital chamber, and the eggs mature in the chamber until they are ready to hatch. The only reliable information I have found was not sure if the caterpillars were deposited after they hatched or if the eggs hatched as soon an they were deposited. (I.F.B. Common, Moths of Australia, 1990).
Some other observers believe they are deposited live. There are of course other members of the animal world that do this. Some types of shark, some fish, some snakes and rays.

The larval food of many of the Monopis moths include animal fibres, feathers, bird droppings, bat and bird guano and similar material.

Sub Family:- TINEINAE
Genus:-  Monopis
Species:- chrysogramma

Not the greatest photo, but I don't see them often.


Monopis icterogastra TINEINAE TINEIDAE

This one is also thought to hatch the eggs within a genital cavity in the female and the caterpillars
are said to be deposited live.

Monopis icterogastra is also known as the Wool Moth.
The larvae of one Monopis species moth was found feeding on soiled sheep wool, others inhabit birds nests.
(See also Monopis chrysogramma above)

Addaea subtessellata

 Addaea subtessellata SICULODINAE THRIDIDAE

This is the only species of the THRIDIDAE family I have ever identified here. Although there may be others in the ever increasing pile of photos in the "to do " folders.

The larval food plant is Mallotus philippensis (RED KAMALA).
See a post on, for Thursday, February 4, 2010

Genus:- Addaea
Species:- subtessellata

This is another moth that has an unusual stance at times.



The Edosa species are common throughout Australia and many of them look very much the same so positive identification is not always possible.
One note I have found says that the larvae have not yet been found, so no information is available on
the biology of these moths. They are also very similar to some species in Oecophoridae, but Tineidae
lack the sharp upturned labial palps.
These moths are tiny and very easy to miss.

Genus:- Edosa
Species:- xystidophora (probably)

Ocrasa decoloralis PYRALINAE PYRALIDAE

Ocrasa decoloralis PYRALINAE PYRALIDAE

I don't have anything on the biology of this moth, however the larvae of another Ocrasa, O. albidalis, are know to skeletonize the dead leaves of Eucalyptus trees. It is possible the larvae of this moth will have similar habits.

Sub Family:- PYRALINAE
Genus:- Ocrasa 
Species:- decoloralis


Spectrotrota fimbrialis EPIPASCHIINAE PYRALIDAE

I don't have anything on its biology. It is fairly wide spread throughout the eastern parts of Australia.
Wing span was about 20mm.

Genus:- Spectrotrota
Species:- fimbrialis

Declining insect numbers

First item this week is an article on the link below. It is another article pointing out the problems that our moths and other insects are having surviving in the current climate across Australia, and the associated food shortage and decline of the animals that use the insects as a food source.

I have mentioned on this Blog a number of times, the dramatic drop in the total number of moths we get at night on the windows.
I know there will be many factors including our current drought, but it is the longer term reduction in insect numbers over a 30 year period that is the real worry.
The loss of certain species can be accounted for by habitat loss and changes in the plant species in the
immediate environment, but there appear to be other factors at work.

Drop in insect numbers have been noted over large parts of Australia and Europe. The evidence world wide is mostly by observation rather than formal research, except in Germany where there has been some long term research done showing a 75% drop in total flying insect biomass in protected areas over 27 years.

These links are deliberately not "click on" links. You can either paste the link into your browser or search out the web sites via normal search methods.

I wonder how many other countries are suffering the same problems with their insects.



This moth is likely to be a grass moth, and we have noticed a drop in these moths that can be directly
attributed to the type and quantity of uncut grasses in the area and the increase in imported grasses taking over from native grasses.
I was not able to find anything specific on its biology.

Genus:- Faveria 
Species:- laiasalis


 Ephestiopsis oenobarella PHYCITINAE PYRALIDAE

Not an easy moth to identify, but it is likely to be Ephestiopsis oenobarella. The best match I was able to find was a photo on Bold systems labeled (IM11-0182) CC BY-NC-SA (2012) CBG Photography Group.
Most likely another grass moth.

Genus:- Ephestiopsis
Species:- oenobarella

Scenedra decoratalis

Scenedra decoratalis PYRALINAE PYRALIDAE

I have not been able to find anything about its biology.
I have included a cross section of the variations we see in the appearance of this moth.

Sub Family:- PYRALINAE
Genus:- Scenedra
Species:- decoratalis 

Click on the photos for a larger view.


Scoparia exhibitalis SCOPARIINAE CRAMBIDAE

Although I originally placed in this moth in PYRALIDAE, I find it now is in CRAMBIDAE. I am not sure if I made a mistake or that over the years the designation has changed.

The members of the sub family SCOPARIINAE are generally said to be moss eaters, often found in moss and lichen. I have no specific information for this particular species.

They are reasonably common in southern Australia. It sometimes surprises people to find that we, at around 27.5 degrees south, as is Brisbane, are in the southern half of Australia.

Genus:- Scoparia
Species:- exhibitalis

Morosaphycita oculiferella

Morosaphycita oculiferella PHYCITINAE PYRALIDAE

Wingspan about 20mm.
I couldn't find anything on its biology.

Genus:- Morosaphycita
Species:- oculiferella


Endotricha mesenterialis PYRALINAE PYRALIDAE

I was not able to find the larval food plant for Australia, but in Malaysia, the family Dipterocarpaceae seems to be the main source. The next level up the botanical tree is the order Malvales and the larval food plants are probably going be in that group.
A plant in the family Guttiferae is also mentioned as a host in West Malaysia.
Wingspan is about 10mm.

Sub Family:- PYRALINAE
Genus:- Endotricha 
Species:- mesenterialis

 Mimaglossa nauplialis

Mimaglossa nauplialis EPIPASCHIINAE PYRALIDAE 

As can be seen from the photo, the moth is about 18mm long so a wing span of about 30mm.
I was not able to find any thing of its biology.

Genus:- Mimaglossa
Species:- nauplialis



The larval food is the dead leaves of Eucalyptus trees, MYRTACEAE. The leaves are sometimes bound together with silk, with several larvae together in the space between. They skeletonising dead leaves, eating the surface of the leaf and leaving the veins.

Some of the adults have two strong horizontal lines on the fore wings and others have little or no markings.

They can also have a dark spot near the leading edge of the fore wing about half way along or a little further.

Sub Family:- PYRALINAE
Genus:- Ocrasa
Species:- albidalis
