Whats a sexual?
Hi, I looked it up and found this paper:"Ant queens adjust egg fertilization to benefit from both sexual and asexual reproduction" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3130223/ ,

It's abstract says:

An enduring problem in evolutionary biology is the near ubiquity of sexual reproduction despite the inherent cost of transmitting only half the parent's genes to progeny. Queens of some ant species circumvent this cost by using selectively both sexual reproduction and parthenogenesis: workers arise from fertilized eggs, while new queens are produced by parthenogenesis. We show that queens of the ant Cataglyphis cursor maximize the transmission rate of their genes by regulating the proportion of fertilized and parthenogenetic eggs laid over time. Parthenogenetic offspring are produced in early spring, when workers raise the brood into sexuals. After the mating period, queens lay mostly fertilized eggs that will be reared as the non-reproductive caste.

What I think that essentially means is that sexuals are the offspring which are produced from parthenogenetic eggs (asexually), they are the new or future "queens", while those produced sexually from fertilized eggs become the workers.

I hope this helps!
