Probably not exactly what you want, but some permutations of group and
|Species should work.

library(lattice)
n= 200
dat = data.frame(X=sample(1:99,n,TRUE), Y=sample(0:1,n,TRUE),
           
Species=sample(c("A","B"),n,TRUE),Group=as.factor(sample(1:3,n,TRUE)))
# avoid criss-cross by ordering
dat = dat[with(dat,order(X,Y,Species,Group)),] 
xyplot(X~Y|Species, group=Group,data=dat,type="l")
