Madagascar - Part 10
Insects of Madagascar are often even more weird than its larger animals. Their diversity in such a relatively small area is stunning: for example, there is about 200 species of dung beetles, all of them endemic. Some are ancient relicts: one genus of ants was found in Jurassic amber from the USA before being discovered on Madagascar. Others are among the world's most beautiful creatures.

Giant comet moth (Argema mittrei), Manja |
Diurnal Urania moths (right) belong to a small ancient genus, with other species in the northern Neotropics. They have asymmetrical wing patterns, unique for each moth. Comet moth (left) has a smaller relative in Africa. |
Sunset moths (Urania madagascariensis), Manja. |

Many Madagascar insects have close relatives on other continents. This was once used as a proof of the movement of continents. But it looks like Madagascar has floated all over the world, collecting fauna from both Americas, Indochina, New Guinea, Africa, India, Australia... Some connections are Gondvanian heritage, others are a mystery. |
Hissing cockroaches (Gromphadorhina dortentosa), Amic. |

Some insects are so perfectly camouflaged that finding them is almost impossible unless they move.

Nefila madagascarensis, world's largest
web-making spider, PN Masoala. |
Spiders, snails, slugs, millipedes, mites, scorpions, freshwater shrimp... each group is an infinitely complex and diverse world, full of surprises. I've never heard of singing crabs, but they exist on Madagascar, and can be easily found by their nighttime calls. As for small soil creatures and parasites, it is sometimes easier to find a new species than an already described one. |

If you think terrestrial leeches are appalling, you are not a true naturalist. These beautiful, energetic creatures are yet another biogeographical mystery, occurring also on the Seychelles, in SE Asia, Australia, and Chile, but not in Africa. In Ranomafana National Park you can meet thousands in one rainy day. Interestingly, there's only one species of freshwater leech on Madagascar. |
