Morphology
Polyergus + rufescens
This is a taxonomic binomial combining a genus name (Polyergus, which signals the slave-making ant group) with a Latin species epithet; if a learner knew that 'rufescens' means 'reddish' the combined meaning (a reddish Polyergus ant) would be derivable. However, the species epithet is Latin and not in the provided dictionary entry (and such Latin epithets are typically unknown to B1 learners), and the formal scientific naming pattern is not a standard everyday English compositional pattern, so the meaning is only partially predictable.
Etymology
Polyergus rufescens comes from old Greek and Latin words: Polyergus combines Greek 'poly' meaning 'many' and 'ergon' meaning 'work', and rufescens is Latin for 'reddish'. The ant is red and it depends on many workers taken from other nests, so the name points to both its colour and its behaviour.
