Expressions of swarm dynamics and ecological characteristics of the species included in this paper. When there is conclusive evidence on presence or absence of a given phenomenon, it is noted as such. Asterisk denotes the possibility based on inconclusive and anecdotal evidence. Unknown denotes the lack of quantitative data.
