Full overview of spatiotemporal activity patterns of single muscle groups within the main mandibular adductor for each species. Numbers in the upper right corner of each graph show fiber quantity (##) and group designation (G #) in the format (## / G #). Activation spreads of muscle groups in the Aeshna/Sympetrum setting show that the dorsal and ventral muscle groups with the lowest activity (G1+2, 8+9) have the largest spread of single fibre activity while muscle groups with a higher overall activity show a comparable low activity spread for their single fibres. Note that activation spread is not a function of modelled fibre quantity per muscle group. In the Anax muscle setting, the medial muscle groups G10-16 show a low activation spread, while activation spread for the main muscle groups G1-9 gradually increases from dorsal to ventral. The Cordulegaster muscle setting is characterized by a higher activation spread for the medial muscle groups (G1-10) compared to Anax. Similar to the Anax setting, activation spread increases from the dorsal to the ventral main muscle groups (G11-19). The distinct patterns mentioned for the three former species/muscle settings are basically not detectable for the Onychogomphus muscle setting. Activation spreads do not show a distinct separation between more medially located muscle groups (G1-13) compared to the lateral main groups. Equally, there is no distinct pattern observable between dorsal and ventral main muscle groups (G14-29).
