TN Butterflies Facebook 2017– An Analysis
District wise species representation
27 out of 32 districts were represented in the forum at least by a post minimum in the year 2017. The districts which missed
out are the Delta districts Thanjavur, Nagapattinam and Thiruvarur and Karur and Tuticorin. However, all the districts had
representation if we consider the period 2014-2017. Districts with maximum no of species representation and contributions
are Coimbatore, Chennai, Erode, Dindigul (thanks to the Kodai survey), Tiruvannamalai and Sivagangai. Other significant con-
tributions are from Trichy, Tiruppur, Salem, Madurai and Virudhunagar. The contributions from Theni and Tirunelveli have
gone down noticeably. Some districts have benefitted by a few diehard butterfly lovers.
Family wise– Month wise species representation
The graph below shows clearly correlates with the weather pattern of the state. A poor monsoon in 2016 resulted in the
drop of species being reported for the first six months in general. The rains from April helped shoot up the counts, and some
species gained undue advantage like Common Emigrants in terms of mass outburst from April to July. The momentum
picked up from July for all species and peaked in October. The butterfly season for Tamil nadu is between September and
November and the data truly reflects the same!
