Such behavior has not been reported for this genus. Unlike other tiger beetles, H. analis may take advantage of termitaries adventitiously, without specializing on them.展开更多

文摘Spot surveys conducted during the early part of the monsoon season in northeastern Thailand indicated territorial hilltopping on termitaries by the tiger beetle,Heptodonta analis. Such behavior has not been reported for this genus. Unlike other tiger beetles, H. analis may take advantage of termitaries adventitiously, without specializing on them.
