Dont know if these two types of critters are related.

Any advice on best how to deal with them please. Especially if it does not
involve expensive and poisonous chemicals. Thanks.

Jake's advice is spot on, but IMO you will get nowhere in the end - just
spend time and money on a pest you cannot win against as it has no
natural enemies in this country.

Either grow your lilies under glass where the pest cannot get at them,
or simply give up growing lilies (and many other members of the
Liliaceae such as Fritillarias), and grow something else.
