Hierarchical clustering analysis of the 42 identified spots.

<p>(<b>a</b>) spots listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0089607#pone-0089607-t001" target="_blank">Table 1</a> were clustered according to their percentage of volume from 1^st to 5^th instar by the method of UPGMA. The spot number is indicated on the right of the heat plot, the protein name is on the left side. Two main clusters were formed. (<b>b</b>) Cluster according to the stages of larvae growth. Numbers “1”, “2”, “3”, “4”, “5” are used instead of the 1^st, 2^nd, 3^rd, 4^th and 5^th instar. The five instars were clustered into three groups.
