feersum beestie v2

Another caterpillar, this time of the elephant hawk moth, trying to find a safe place in the grass and leaves. When disturbed this enormous caterpillar rears its head and waves about in an attempt to look sinister. Its head is actually much smaller than it looks, and it retreats into the bulge on top of which are the two large simulated eyes.

feersum beastie


This is the caterpillar of the pale tussock moth (see link for earlier post showing the moth). The colours are striking and serve to warn predators that they are distasteful to eat. At this time of the year they are about to spin strong double shelled cocoons and then hibernate over winter before emrging as adult moths in May and June. There is always something new to see!

autumn is upon us


Autumn is here even though it is warm and sunny.  Early in the morning the mist lends a mysterious feel to the lane. Meanwhile stinkhorns are out. When they first emerge the head is covered in a glistening grey green slimy skin. It has a very pungent smell which attracts flies. This one was covered in blue flies, many of which flew away at the approach of the camera lens, but enough remained to illustrate how effective this method of spore dispersal is.

moulty


Something that caught our eye this morning was seed heads of grass bent over by silk. As can be seen in the bottom picture the cast-off shell of a spider is attached to the web on the outside, and inside the silk cocoon one can see the tips of the legs of the previous owner (I guess) in its new skin. I am not sure whether this is for protection from predators while the exoskeleton hardens or some sort of devious spider trap.

it's just not cricket


the top picture is of water crickets (Velia caprai, see link) bombing around. They can travel faster by spitting on the surface of the water. They also make ripples that are relatively huge given their diminutive size. Below a water cricket has been caught by a spider that appears to be able to walk on water.



done buzzin


This cold damp bumblebee was found this morning hanging by one foot from a scabious seed head, about to fall stuporose into the meadow grass below and be consumed by the many small predators there-in. Foraging bumblebees often run out of fuel like this especially first thing on colder mornings. In its dopey state it was easy enough to move the bee to a fresh flower head, where it quickly started feeding and refuelling to start another day's work.

something lurking in the woodshed


An unusual sight locally at the best of times, a humming bird moth taking an interest in our woodshed, and a photograph (1/3200 at f8) taken in 2012 that shows their amazing ability to hover while feeding on nectar.

pony nekking


Ponies on Bodmin Moor this (lovely) morning. The stack of Kit Hill can just be made out to the left on the far horizon. The bracken is turning, and the leaves are falling, Autumn is upon us already.

crunchie bar

continuing the close up season, this caterpillar was found munching on the plastic netting protecting our rosemary shrubs from the hordes of ravenous rabbits. I haven't been able to identify to which species it belongs.

Lists of Gold



The little stream that rises at the duckpond in Venterdon runs the length of the valley below Old Mill where it takes a meandering course before gathering pace and running through Luckett into the Tamar. Today golden ringed dragonflies were patrolling up and down the path that runs on the northern side of the stream. It was bathed in warm sunshine. Himalayan balsam (that has spread like mad in this area) lines either side of the path, and bird's foot trefoil and eyebright grow on its floor. This creates a natural space for jousting. The males fly up and down, and when they meet engage in high speed agile aerial combat. In WW2 fights between fighter planes were always referred to as dog fights; dragonfly fights would have been more accurate. After a fight the combatants land to take a breather and allow some close up photography. At the same time a couple of male common blue butterflies were also engaged in territorial warfare. In previous years this path was lined by more familiar plants like valerian and hemp agrimony. I am not sure how much of a problem Himalayan balsam is, but it would be a mighty undertaking now to get rid of it.

The close up shows the amazing pixellation of the dragonfly's compound eyes.
