The Tmetolophota blenheimensis is a special type of moth. It belongs to a group of moths called Noctuidae, often known as owlet moths. This moth is very unique because it is endemic to New Zealand. This means it can only be found there!
Because it is so rare, the Department of Conservation has given it a special status. They call it "At Risk, Naturally Uncommon." This helps people know that this moth needs protection.

How Scientists Name This Moth
This moth was first described in 1883 by a scientist named Richard William Fereday. He used a female moth collected near Napier to give it a name. He first called it Leucania blenheimensis.
Later, in 1887, another scientist, Edward Meyrick, described the male moth. A well-known entomologist, George Hudson, also wrote about and drew this moth in his books.
Over the years, scientists sometimes change how they classify animals. In 1971, John S. Dugdale moved this moth into a new group, the Tmetolophota genus. More recently, in 2019, Robert J. B. Hoare studied New Zealand moths again. He suggested that this moth should be placed in the Ichneutica genus.
What the Blenheimensis Moth Looks Like
This moth has a wingspan of about 1.5 inches (about 3.8 cm). Its front wings are a creamy color. You can see darker lines on them, which are the veins.
The front wings also have three faint black dots. Near the edge, there are more black dots in a curved line. The very edge of the wing is shaded with dark greyish-brown. The fuzzy parts of the wings, called cilia, are also dark greyish-brown.
The back wings of the moth are grey. They are a bit lighter in color closer to where they connect to the moth's body. The cilia on the back wings are also grey.
Where the Blenheimensis Moth Lives
As we mentioned, this moth is only found in New Zealand. It lives in several different areas across the country. These include the Hawkes Bay, Marlborough, Dunedin, Otago Lakes, Southland, and Stewart Island.
Scientists have collected specimens of this moth from many places. These include the area where it was first found, Meanee. Other locations are the Denniston plateau, Blenheim, Dunedin, Lake Wakatipu, and the Routeburn.
Life Cycle and Behavior
The Tmetolophota blenheimensis moth is active during the warmer months. You can see it flying from November all the way through March.
Scientists have caught these moths using "sugar traps." These traps use a sweet mixture to attract the moths, making them easier to study.
Host Plants and Habitat
The young moths, called larvae or caterpillars, need specific plants to eat. For this moth, scientists believe the caterpillars likely eat a plant called pīngao. This plant is also known as golden sand sedge.
Interestingly, pīngao is no longer found in the area where this moth was first discovered. This shows how important it is to protect both the moths and their food sources.
Why This Moth Needs Protection
The Tmetolophota blenheimensis moth has a special conservation status. It is listed as "At Risk, Naturally Uncommon" under the New Zealand Threat Classification System.
This means that while it might not be in immediate danger of disappearing, it is naturally rare. It needs our help to make sure its habitats are safe and that it can continue to thrive in New Zealand.
