I think you have the striped cucumber beetle, a predictable invader on cucumber plants many years. Have a look: http://www.hort.uconn.edu/Ipm/veg/htms/cukbtltcrop.htm The best non-chemical method of control is prevention, growing young plants under floating row covers where beetles can’t get in, and only opening the covers for pollination purposes. Besides feeding on plant parts, the beetles move around the plants and transmit bacterial wilt and other diseases. Sometimes mature plants can withstand some feeding activity; other times, it is too much for the plants. I suggest that you sown another crop of bush (fast-growing) cukes, and do so in another are of the garden, under a row-cover fabric. Some gardeners hand-pick the beetles and known them into a bucket or can water to drown them, but depending on how heavy your infestation is, that may or may not be worth it. It’s only early July; start again. There are also some less-toxic dusts and sprays made from natural materials, but they are not NON-toxic, remember, so caution is still advised: http://www.gardensalive.com/search.asp?ss=cucumber+beetle&x=0&y=0
