Proteins that were manually categorized by function were subjected to average-linkage clustering (Figure 3). Separate analyses were done for solid tissue and hemolymph. Only proteins that were quantified for at least 4 out of 5 days and protein classes that had at least 5 members were considered for enrichment analysis. Classes with at least 50% enrichment in nodes with a correlation of >0.8 are considered significant and shown.
