Caterpillar suspended in mid-air

This caterpillar was part of a colony of some 20 or so individuals enclosed in silk threads. On being disturbed it threw itself out on a invisible silken thread and hung suspended in the air.

Diving beetle (Dytiscus marginalis)

An unused swimming pool becomes the home of many freshwater plants and animals. Insects of many types, such as beetles (Coleoptera), true bugs (Heteroptera), and fly larvae (Diptera), can be observed swimming in unused swimming pools.

Here a Dytiscus beetle has flown in from a neighbouring pond to make the pool its temporary home. It surfaces rear-end first to breathe before diving again to hunt for prey. Diving beetles are excellent swimmers, their bodies are streamlined, and their flattened rear legs, which bear two rows of “swimming” hairs (see photo), can generate powereful strokes.

A disused swimming pool is great place to observe freshwater wildlife because it is easily accessible, its edges are free from terrestrial vegetation which often make it difficult to see. In addition to this the blue of the pool allows us see creatures that we might not have noticed - check out the spiral of green algae in the photo.

Two-tailed Pasha (Charaxes jasius)

dsc_0121_medium.jpg

When on the wing, this large and powerful butterfly resembles more a small bird than a butterfly due the speed and the nature of its flight. This no doubt serves it well since it has the habit of establishing and defending hilltop territories otherwise known as “hilltoping” (hilltops serve as mate-encounter sites not only for this species but also for many other insects).

Ideally, I would have liked to photograph it with its wings open, but when it did eventually decide to land (several times on animal dung), it immediately placed its wings in an upright position. This was the best shot I could get - naturally I avoided to photograph it on dung!

Charaxes jasius’ larval foodplant is the strawberry tree (Arbutus unedo) but it is also attracted to fermenting fruit, animal dung, and alcohol in the form of beer and wine!

Now watch a short educational film (in French) on the life-cycle of Charaxes jasius.

Checkered beetle (Trichodes alvearius)

This colourful little beetle may look innocent enough as goes about collecting nectar - its private life, however, is something other. As a larva it lives in bee hives and feeds on young bees.

A similar species is Trichodes apiarius.
