Tanka is haiku that focuses on nature and season, but is a bit longer than the traditional haiku of three lines with 5-7-5 syllables. A tanka consists of five lines for a total of 31 syllables. The syllables per line are according to the pattern 5 -7 -5 – 7 – 7.
Here is a tanka I wrote for a chapter in Broken Dolls, and is a metaphor for a love that is begun, though the lovers know it can never continue:
A caterpillar weaves
its cocoon, where a lovely
butterfly grows. Though
all the while, it knows too well,
its end will come too soon.
Any haikus or tankas about butterflies out there?
