My immediate reaction is that this is likely damage caused by varroa.
I see a number of these particularly later in the year as the
infestation gets heavy. The mites feed on the larvae, which then
fail to develop fully, seen typically as stunted growth of abdomen
and/or wings. If I'm right, infestation is probably quite heavy
and you should be dealing with it.
