Propylea vs Oenopia larvae

ID help for the larvae of some Propylea and Oenopia species
Propylea has the pale markings on the dorsum of the thorax hourglass shaped, vs Oenopia bell shaped.
The pale colour on Propylea is _usually_ white, but orange specimen do occur
The pale colour on Oenopia is _usually_ orange, but white specimen do occur
The difference between the two Oenopia is subtle: On O. impustulata the pale patches along the centre line are mostly formed by a narrow cross bar at the hind margin of each segment vs conglobata with a more clearly developed patch over the whole length of the segment (again: sligtly bell shaped). This is normally especially evident on abdomen segment 3, but exceptions/aberrations can make this a tad iffy to use (look at the average markings over the whole of the central stripe).
