[saccolaimus]

Hi!! I really love this picture and it is very cute but unfortunately the identification seems incorrect, so small correction:

This bat is certainly a species of Pipistrellus

This is identifiable and differentiates from Nyctalus by the tragus (the little flesh projection on the base of the ear covering a small part of the front). Nyctalus has a bean-shaped tragus that is a lot wider than long. Pipistrelles have tragi longer than wide although still short compared to Myotis. Nyctalus ear structures are also rather wrinkly compared to pipistrelles. The snout is also not very broad like in noctules and rather narrow compared to Nyctalus leisleri. The ear skin’s connection to the mouth area also isn’t very visible. It may be hard to form the exact picture in mind from just a few descriptions but looking at image comparisons will certainly help. All of this combined tells us this is a pipistrelle.

I am not able to fully identify the exact pipistrelle this little bat is but if i had to guess it would be a common or soprano but we are not able to differentiate these well if we do not have a sonogram of the echolocation calls. Sometimes, the vein patterns in the plagiopatagium can tell us cues to which one it is but even that can be variable between the two. The darkened face suggests to me it may lean more to a common (Pipistrellus pipistrellus), but this is still variable within the species. If you can provide forearm measurements this can possibly also rule Pipistrellus nathusii in or out.

So i would confirm this is a bat in the genus Pipistrellus. Nevertheless, great picture of a wonderfully cute bat!!!

Here these images should help show the general differences between Nyctalus and Pipistrellus. I hope this helps!
