All Things Wierd and Wonderful

This time we’re exploring the weird, the wonderful & one or two myths about creatures both common & rare that live alongside us in the PO. 


How do snakes eat large prey?

They don’t dislocate their jaws. The upper and lower jaws are connected by a super-stretchy ligament which allows them to open their mouths wide enough to swallow whole prey much bigger than themselves. Digestive juices subsequently break down the animal. Yum. 

The non-venomous Ladder snake (couleuvre à échelons) – common here – can gulp down rabbits and birds.


What’s the life expectancy of a butterfly?

It would be too sad if these flying jewels lived for one day only. Happily, most survive for several weeks and some species hibernate, such as the PO’s stunning Cleopatra (Citron de Provence), finding shelter in plants like ivy.

Not all butterflies feed on flowers

Arguably our most spectacular butterfly, the two-tailed Pasha (Nymphale de l’arbousier) gets its French name because the caterpillars feed exclusively on Strawberry trees (l’arbousier).

The butterfly, however, only drinks nectar from fruit – never flowers. If you have a fig tree, why not leave some fruit for them and other insects to enjoy?  

Unusually, it’s the underside of the Two-tailed Pasha’s wings that’s most striking. Easy to mistake for a small bird when seen in flight from the corner of your eye.

Can insects hear?

Yes. Hearing can help them with communication, navigation and defence. Many have the same mechanism as the eardrum of humans and other animals, although it’s not necessarily on their head. In the bush cricket, it’s on their legs!  

Crickets and grasshoppers, along with butterfly and moth caterpillars, also use small, stiff hairs to sense sound vibrations. Caterpillars often respond to sound by exhibiting defensive behaviours; some will stop moving while others will contract and rear up.  

Weirder still, certain hawk moths have a structure in their mouths that enables them to hear ultrasonic sounds such as those produced by echo-locating bats.  

And some insects possess a group of sensory cells on their antennae that collect auditory information in vibrations. Bees use it to help locate food sources.

Where do they sleep?

For most, a nest is only constructed to hold eggs and chicks. Outside the breeding season songbirds will roost in trees or some kind of vegetation.

Cavity-nesters, such as some owls and woodpeckers (hiboux et pics), may use the same hole to sleep in overnight as they did for nesting, but they usually have a number of possible roosting sites in their territories.  

In wintertime here, the orchards and vineyards are popular feeding sites for mixed flocks of goldfinches, chaffinches and linnets (chardonnerets élégantspinsons des arbreslinottes mélodieuses). They will form communal roosts several kilometres away, in the inner branches of trees (especially oaks).  

Throughout the summer, swallows and house martins (hirondelles rustiques et hirondelles de fenêtre) have several broods in the same mud nests under the eaves of village houses. In Africa for the winter, however, they find safety in numbers in shared roosts, often at reedbed sites where they perch together on reed stems.

Black squirrels in the P-O?

Not really. The only species here is the red squirrel (écureuil roux) – it’s just that some are so dark they appear black. 

What’s that cat?

The genet (genette commune) was introduced by Moors in the Middle Ages but is now considered indigenous. Though common here, they are rarely seen because they’re nocturnal.

They can squeeze their flexible bodies through any opening larger than their heads, and have retractable claws – useful for climbing trees to hunt birds. But their diet is mixed and also includes small mammals, bats, birds’ eggs, frogs, millipedes, centipedes, scorpions and fruits.

Wild cats (chats sauvages) live in remote wooded areas. They are distinguishable from the normal tabby by their bigger size and three broad, black stripes towards the end of their thick tail. These are rare and very shy but do cross-breed with domestic cats.

Foxes kill for fun, don’t they?

Foxes (renards) are unlikely to view killing as a sport in the same way some humans do, but their predatory instinct is so strong, they’ll kill any available surplus prey – especially if it’s an easy catch.

If possible, they may bury some or all of the surplus, to eat another time when hunting is less good. It’s a successful survival strategy. After taking one bird from a henhouse they may intend to keep returning for the rest, but often don’t get the chance because the owner will have cleared up the corpses. 

Foxy Facts
  • Foxes are related to wolves, jackals and dogs but are the only members of the dog family that can climb trees 
  • However, unlike dogs, they have vertically-oriented pupils which allow them to see in dim light. So, like cats, they are most active after sundown 
  • Also like cats, they have sensitive whiskers and spines on their tongues  


Not so friendly dolphins?

Infrequently spotted in this part of the Med, dolphins (dauphins) have a dark side: they sometimes attack and kill porpoises – for no reason apparent to us humans – but don’t eat them. And males are also prone to sexual harassment and infanticide!

Octopussy Facts
  • Only molluscs, crustaceans, and some fish need fear octopuses (poulpes) – they don’t harm us
  • Their brains have signs of complexity and electrical patterns similar to those of humans
  • But while the human brain can be seen as a central controller, all 8 limbs of an octopus can act on their own or in coordination with one another
  • Among other displays of intelligence, these creatures can build shelters for themselves with stones or shells, & the Mimic octopus can change its shape, movement and behavior to impersonate at least 15 different – often venomous – species
  • And yet, after mating, males will die within a few weeks. The females protect their eggs for several months but die once the eggs have hatched. What a waste of brain power!
