Hipposideros larvatus, a large, cave-roosting bat.
Hi Folks,
Well we had quite a busy time last night! The traps are still on the main trail but off grid (traps set: KL0642, KL0643, KL0644, KL0645, KL0648, KL0649, KL0650, KL0665, KL0701, KL0703, KL0709, KL0711, with KL0659 closed due to ants). It is quite a walk to get to them now. We leave around 8 pm and reach the traps by 8.30 pm or so. The lactating females are processed in the field and released immediately, so that they can get back to feed their pups. The other bats are brought back to the field station so that we can process them in a bit more comfort and so that Julie and I can use them for flight experiments and temperature experiments. So by the time we got back to the house last night it was around 10.30 pm, and we still had a lot of work to do!
We had some nice captures last night, Hipposideros larvatus is one of the larger Hipposideros species (FA 57.1-61.8 mm, Wt 14.3-20.5 g), with brown or orangey fur. It has three lateral leaflets (like Hipposidero diadema), and is commonly found roosting in limestone caves. We don’t catch it that often in the forest here at Krau, I think there aren’t many roosts close enough to our bit of forest.
Emballonura monticola, a small member of the family Emballonuridae
In the morning we had a female, lactating Emballonura monticola, the smallest member of a new family for you, the Emballonuridae (or Sheath-tailed bats). It has dark brown fur, and quite large eyes as you can see in the photo. The forearm ranges between 38-47 mm and weight 4.0-6.0g). The Emballonuridae have a very distinctive tail — instead of going all the way to the end of the tail membrane, it sticks up out of the membrane half way down in a little sheath (which is how they get their English name, the Sheath-tailed bats). Emballonura monticola likes to feed at the forest edges and in tree fall gaps, so we don’t usually get it in the traps. However, it does like to roost in small rock caves, or along the side of fallen logs in the forest understory, so we occasionally catch them when we have a harp trap near a roost.
