A great news has just arrived from India!

 

   Ludlow's Bhutan Glory (Bhutanitis ludlowi) was discovered from Arunachal Pradesh, India. This magnificent swallowtail was re-discovered after almost 80-year absence in 2009. This species was thought to be endemic to small area of eastern Bhutan. In 2011, our society has a joint research with Bhutanese government and unveiled its biology.

 

   The observation and finding in our survey was described in our journal, Butterflies No.60.

[Movie File] Ovipositional behavior of Vanessa indica

[Movie File]　Ovipositional behavior of Vanessa indica　
   It is amazing that butterflies can select their foodplants correctly to lay eggs from numerous kinds of plants growing in the field. Once the mother butterfly successfully comes near to her foodplant then she starts to drum the surfice of nearby leaves at random to find the real one. This is because the butterfly has the chemotactile receptor on its foretarsus so it tries to "taste" the plant chemically by this behavior.

　In the case of Nymphalid butterfly, it uses the forelegs which are usually folded on its thorax. This video is the female of Indian Admiral (Vanessa indica) which is drumming its foodplant, Ramie (Boehmeria nivea) by its forelegs. In the field, it is not easy to observe such an interesting behavior.

An abberant form of Common Bluebottle (Graphium sarpedon)

   Common bluebottle (Graphium sarpedon) is known to have an abberant form which lacks almost all its bluish spots on its wings. This blackish form is very rare but found in many places from old days. Checking the wing patterns of this form carefully, one can find out the one bluish spot on its each forewing's apex usually remains although all the other bluish spots are missing. The reason is not certain but it is possible that this spot may have some special meaning.
