I walked my favorite butterfly trail in Elk Island National Park today during a late afternoon sunny break. I was happy to find these four beauties. I thank mattbpics for his great images of Moths and inspiring me to pay more attention to them.

The beautiful and scarce Argent and Sable moth.


One from the archives, but a very memorable moment as this normally flighty moth gave me an unusual opportunity to get a few photos of it in a Wiltshire woodland.

Vaivorinis sprindžius (Rheumaptera hastata)

Zeldzaam in Nederland.

Karakteristiek zijn de witte ‘speerpunten’ die vanuit de brede buitenste witte dwarsband de vleugelzoom insteken.

Vrij zeldzaam. Komt vrijwel alleen voor op de Veluwe en in Noord-Brabant. RL: gevoelig.

Habitat. Vooral open (gekapte) plekken in het bos en moerassen.

Waardplanten. Berk en bosbes; mogelijk ook gagel.

Vliegtijd en gedrag. Eind april-begin augustus in één generatie. De vlinders zijn overdag actief, vooral bij zonnig of warm weer. De mannetjes kunnen worden waargenomen terwijl ze door middel van geur een vrouwtje proberen op te sporen; de vrouwtjes worden soms ei-afzettend waargenomen.


Rare in the Netherlands.

Argent and sable moths or Rheumaptera hastata are day flying moths of the Geometridae family, with distinctive black and white colourings. They tend to live on wetlands and hillsides. The larvae spin together the leaves of their food plants (such as birch and bog myrtle) to form their cocoons. It was named argent and sable in 1778. Argent and sable refers to the heraldic color names for black and white. Their distribution is Holarctic.

A stunning moth, and a new species for me from last weekend.

Ik ben erg blij met deze spanner want hij is zeer zeldzaam in Nederland

I am very glad with this night-moth because it is a very rare species in the Netherlands

A stunning moth, and a new species for me from last weekend.

The Argent and Sable (Rheumaptera hastata) is a scarce day-flying moth. Argent is the term used in heraldry for a silvery white colour and sable was used for black, named after the colour of the Russian marten-like animal. Its scientific name Rheumaptera means river-winged, maybe because the markings look like rocks in a river. Hastata means spear-shaped, apparently from one of the wing markings, probably the white ones in the black border, which do look a bit like spear heads. It is found locally throughout Britain, but is commonest in Scotland. There are just a couple of sites in Yorkshire, which seems odd as its main larval foodplant is birch, although it also feeds on the much more localised Bog Myrtle.

British and European butterflies and moths (Macrolepidoptera)

London,E. Nister;[1895]

Argent and sable are heraldic terms that

mean ‘white and black’. The white spear-shaped markings

in the outer black band give rise to this species’ scientific

name ‘hastata’ from the Latin word hasta meaning spear.

The UK government has listed the Argent & Sable

as a UK Biodiversity Action Plan Priority

This sharp-looking little moth was abundant here today. Even though it's a moth, they fly during the day! Caterpillars feed on touch-me-not leaves.

Rheumaptera hastata


What I thought was a butterfly in my backyard turns out to be a moth and not a nice one to have. This moth turns out to be a pest defoliator of birch trees here in Alaska. So, while it's a nice photo of one, I'd just as well hope not to see many more!

This beautiful moth is now extinct in Sussex and has been now for many years. On an unsuccessful trip to see Marsh Fritillary this was compensation for missing out on the butterfly. Although I have seen these a couple of times at the same site I've never had one pose as well for me.

From Whixall moss

I managed to get close to this Argent and Sable Moth (Rheumaptera hastata) on Fenns and Whixall Moss yesterday. Whilst I see them around a lot, finding one at rest, let along getting close enough for a frame filling shot is difficult. The light was a bit oblique, and not ideal, but at least I got close to this one. They are a nationally scarce moth.

Moth - Rheumaptera hastata

Spear-marked Black. Photographed at Raven Lake, Kawartha Lakes, Ontario on 5 June 2010.

This is the first time I've ever got close enough to get a shot of this stunning beauty. She gave us the run around while prospecting for oviposition sites on the underside of Birch leaves! She is also sensitive to the autofocus pulse [as are other species such as Burnet Companion] so I ended up having to focus manually to prevent her flying off every time I half depressed the shutter release!! Bentley Wood, Wiltshire, UK. 2011-05-25.

This beautiful day flying moth is classified as Nationally Scarce in Great Britain mainly due to the decline in coppicing.

A lot of work has been done on this reserve at Catcott in Somerset by Natural England and the Somerset Wildlife Trust volunteers to encourage the comeback of the Argent and Sable Moth.

It can be spotted on warm sunny days between May and July.

Argent & Sable relates to the colours: Argent meaning silvery-white and Sable meaning black.

It has a single brood and lays its eggs on Birch Leaves or Bog Myrtle which is the plant that this one was photographed on.

The larvae appear from July to August: It spins two or three leaves together and feeds from within the chamber. The pupal stages over-winters amongst moss or in spun leaves.

The caterpillar is dark green with a black head and a line down it's back.
