Going back to your Elephant Hawk moth caterpillar Mickoo: here's one we reared back in 2018...
Most butterfly and moth species are specialists, feeding only on particular plant types. This is mainly due to peculiar adaptations that enable the caterpillars to tolerate various chemical defences that the majority of plants produce. While some species use subtle camouflage to disguise themselves amongst their food plants, others brazenly deploy scare tactics - as this wonderful beast does!
The Elephant Hawk larvae normally feeds on Willowherb, but sometimes can be found living on Fuchsia in our gardens!
During our care of a couple of specimens, I was surprised to discover a really neat, and possibly unique trick: At first, the creature feeds just like any other and grows at an incredible, but predictable rate. However. when it reaches a certain size and weight it cannot then reach the flowers and seed pods, it's apparent favourite part of the plant, far out on slender stems that would not otherwise support it. The solution is to hold fast at the rear end on a thicker branch, stretch out and grab the nearest flexible one, haul it in and bite a little vee shaped chunk to create a folding point that it could bend towards itself. It would repeat that as many times as required to finally bring the delicious tip down to a comfortable feeding position!! One of those bends can be seen at the left in the above image.
After wintering as a pupae, the resulting moth is a delight, and very much one among my favourites...
The glorious thing is not just pretty in pink, nor is it just superbly aerodynamic and built for speed, but apparently it comes with a suite of countermeasures to avoid incoming missiles (of the bat variety) as well!!
Oh dear, as humans, we think we are so clever at inventing stuff...?!!
