Can silkworms eat beetroot leaves?
Apparently yes, silkworms can/will eat beetroot leaves but not if they have already been eating mulberry leaves. But this is hearsay for me. I have raised them on lettuce leaves from start to finish, however.
I have read one article which says yes but two which say no. I would err of the side of caution and not feed the leaves but you can feed the beetroot bulb ok (it may make the bunny pee red though) See http://www.houserabbit.co.uk/resources/content/leaflet_pdfs/going_green_oct_06.pdf (link working 17/9/08)
