Ladybirds in France including the Asian Harlequin Ladybird


Every year in autumn and spring there are articles in the media, especially in the UK, about the Asian Ladybird, Harmonia axyridis, or Harlequin Ladybird as it is known, one of several thousand different non native species introduced in both France and the UK although only a few are ladybirds. This species is generally regarded as the most invasive ladybird on Earth and although they undoubtedly have an environmental impact due to their high breeding and survival rate combined with their voracious appetite most experts are of the opinion that they are now so abundant that there is little if any point in killing them.


Harlequin ladybirds, above, are extremely variable but most have a clearly defined "M" or "W" on the pronotum.

Although they feed most commonly on aphids they have a wide food range that includes scale insects, adelgids, the eggs and larvae of butterflies and moths, many other small insects including other ladybirds, pollen, nectar, and sugary fluids, including honeydew and the juice from ripe fruits bringing them into direct competition with native species of Ladybird many of which are already under pressure resulting from all the usual reasons, habitat loss and pesticide use being uppermost.

The risk as always that comes from articles in the media and the consequent sharing on social media is that some people will unwittingly start killing anything that they don’t recognise as the stereotypical image of a Ladybird, generally the most common of which is the Red and Black spotted 7 spot ladybird, and there are too many people already locked into a “kill everything that isn’t a butterfly” mode of thinking.

To move on, there are 90 or more species of native Ladybird in France most of which wouldn’t be recognised as such. Some are brown, some black, some yellow and black, some black and red, some orange and perhaps not surprisingly many are highly selective about where they live and what they eat with many being vegetarian.

It would be difficult here to include that number of native species, so I have listed a few here to give some idea of just how different they are. 

Kidney-spot ladybird (Chilocorus renipustulatus) Black body with large red spot on each wing case, feeds on scale insects on the bark of trees.

Pine ladybird (Exochomus 4-pustulatus) Usually elytra are black with two larger red comma-shaped spots and two smaller red round or oval spots, feeds on aphids and scale insects.

Heather ladybird (Chilocorus 2-pustulatus) Black with 2 to 6 red spots feeds on scale insects.

16-spot ladybird (Tytthaspis 16-punctata) Beige with black spots. Feeds on Aphids, Pollen, nectar and fungi. Can overwinter in large numbers, 50 or more in one cluster.

Orange ladybird (Halyzia 16-guttata) Orange Ladybirds can be bright yellow or orange in colour with 16 creamy spots. Feeds on mildew.

22-spot ladybird (Psyllobora 22-punctata). Bright yellow with 22 black spots. Feeds on Mildews

24 spot ladybird (Subcoccinella vigintiquattuorpunctata) Sometimes known as the Alfalfa Ladybird. Orange –red, number of spots may vary. Feeds on a variety of plants including Campions, vetches, trefoils, chickweed and plantains among others. They will also take grasses and in France can be a pest of lucerne.

Hieroglyphic ladybird (Coccinella hieroglyphica) brown or black with black stripes, spots and patches. Feeds on larvae of Heather leaf beetle.

Bryony ladybird (Henosepilachna argus) Orange red with 11 black spots. Feeds on White bryony and plants of the Melon family.

28-spotted potato ladybird (Henosepilachna vigintioctopunctata) Orange with 28 spots feeds on the foliage of potatoes and other solanaceous crops.

Gendarmes are also Red and Black bugs, (Fire bugs), in France, not just Police personnel.

Fire bug Pyrrhocoris apterus le Pyrrhocore or Gendarme Many will know this highly successful common bug by the name of Gendarme or perhaps, depending on the region, names such as Suisse, Soldat, Punaise rouge, Cherche-midi or Punaise au corps de feu , all of which are widely used French vernacular names for this colourful insect. As most people will have noticed the "gendarmes" are gregarious and as such live in colonies, which can be described as "gendarmeries", and can number several hundred or even thousands of individuals. Their Black and Red colouration apparently contains a substance that gives them some immunity from predation and as such they make no attempt to hide and even have a very pronounced propensity for collective sunbathing, hence the name of  " Cherche-midi " . Even in winter on a warm day a sunny stone wall or tree trunk will see them out and about. Click on photos to enlarge Being well equipped defensively ...

Deaths head hawkmoth and Great Peacock moth.

OK, size isn’t everything but the two largest moths we find in France are quite spectacular in both adult form and caterpillar and as such I think are worth a mention, they rarely fail to rise a "wow" when someone finds one. The Great Peacock Moth Saturnia pyri is the larger of the two and is Euorope largest moth with a wingspan of between 100 and 150mm, (4 to 6 inches), although some texts suggest that 200mm, (8inches), is possible. Click on images to enlarge Great Peacock Moth on my hand     This is a species with only one generation a year with the adults usually emerging from mid April to mid May when they devote their short life entirely to reproduction as they live for perhaps 7 days and have no requirement to take nutrition.

House Centipede - la Scutigére, (Scutigera coleoptrata) in France

Older French stone built houses invariably play host to a number of species and that includes these fascinating little guests although not all people are thrilled by their presence or their speed when they get a move on reaching speeds of up to 0.4 meters per second. Although in everyday usage they are called a centipede or “hundred feet” they actually only have 15 pairs of legs when fully grown giving them 30 legs. The last 2 legs are particularly long, longer in fact than their antennae reaching twice the length of the body and can be nearly 6 cm. They use these long legs to form a kind of lasso which is one of the methods they use to capture prey. Note that the common terms centipede and millipede are never meant to be factual and both are grouped together as myriapods or very many-footed. Eggs are laid in spring and the larvae when they hatch look like miniature versions of the adult but with only 4 pairs of legs. They gain a new pair with the first moult and t...
