Pointed Line Blue

Ionolyce helicon merguiana


Lycaenidae; Lycaeninae; Polyommatini; Ionolyce helicon merguiana Moore 1884. Ionolyce helicon is described as follows: "Dorsal surface of male dark purple and without markings. Whereas in female, dorsum brownish with a bluish-purple tinge at the wing bases. Ventral surface of both wings with dull greyish-brown and white striae. Eye spot at tornus tipped with orange ring. There is a fine white-tipped tail. Caterpillar greenish with pale green markings. Host plants are Allophylus cobbe and Entada phaseoloides. Pupa mottled brown with dark markings." Wikipedia. This is a helpful description, but rather disappointingly the Philippines is not included in the distribution of this ssp. when its presence here is documented by Philippine Lepidoptera.


This Pointed Line Blue was spotted on a large growth of Tropical White Weed (Ageratum conyzoides) which sits right at a point where the boundaries of 4 rice fields converge. So it is in a great spot for all manner of insects to to visit, not only during the rice growing season, but also the dry season.


This Ageratum conyzoides is one of my favourite plants to visit when I want to see some butterflies. The uncropped picture included above is just to show this little Pointed Line Blue having the time of his life in A. conyzoides paradise.
