Figure 3.

Ancestral state reconstructions of selected traits in the evolutionary history of Blattodea, represented by a simplified tree. Reconstructions of: (a) mode of ootheca formation, (b) ootheca laying behavioural sequence, (c) type of parental care post-oviposition, (d) body shape (length to width ratio), (e) hindwing folding type, and (f) phallomere symmetry. Solidly coloured branches represent the state for that lineage or tip. Dashed branches or no colouration represent uncertain states. States not applicable to the taxon are in grey. Full reconstructions of all traits are given in electronic supplementary material, S3.
