After last years rains and the late snows of winter, this summer has been a really great one for British butterflies. Together August has now pertained to an end, and also summer technically turns into autumn, I believed it to be time for another butterfly post. In particular, I want to write about one that the stranger things about these beautiful little creatures: while they all have actually six legs, most butterflies in one family, the Nymphalidae, only really use four of them.

All the photos in this write-up were bring away by my dad during a recent butterfly-watching walk us both go on. Please ask and also link-back if you desire to usage them!

There are approximately 59-ish types of butterfly in the UK depending on how numerous you decide are now extinct and also 26 that them space in the Nymphalidae family. Choose all insects, butterflies have actually three bag of distinct segmented foot attached to the thorax. The snapshot below reflects a huge White butterfly (often referred to as the cabbage white) i beg your pardon is no a Nymphalidae and below that is body room three white jointed foot clinging ~ above the flower below. The various other three legs space on the various other side. (Click top top the image to obtain a enlarge version).

The Nymphalidae are the largest and most exceptional of the butterflies in the UK - containing the many recognisable varieties including the Red Admirals, Peacocks and Painted Ladies. For these butterflies only the last four of the six legs are provided for stand on. The front two are small and vestigial, tucked up near the head, and no much longer used as legs. The photo below mirrors a grassland Brown which, if friend look closely, is using just two foot to sit ~ above the leaf below, contrasted with the large White butterfly above. Once again, click the photo to acquire a bigger and also clearer image.

So why don"t the Nymphalidae usage their front 2 legs? there doesn"t seem to it is in a clear and also obvious answer. That isn"t due to the fact that they"re little butterflies and therefore don"t require the extra assistance - Nymphalidae are all fairly large and common across the world. In some varieties the tiny front foot have small brushes and also hairs that the butterflies deserve to use to sense smell and taste (which is why they have the nickname that "brush-footed butterflies"), for this reason it can be the the Nymphalidae have chose to use 2 of their legs to boost signalling and communication, and spend the rest of the time where they"re not flying balancing on just four.

Butterfly numbers will begin to drop as the autumn properly kicks in, so it"s ago to the on regular basis scheduled bacteria for the following post.
