Yes ladybug larvae look strange...
especially the solid black ladybug larvae...
I don't remove insects... as many more are beneficial than harmful...
I watch out for grasshoppers, spider mites, whitefly, boring beetles.... Ants will usually lead you to aphids and mites on your plants as they work together
Fortunately I have a lot of ladybugs in the bushes up the hill...
Right now my only issues are slugs....
Buds are so sticky that the slugs secrete more of that slime to get across it... so I hate seeing big snots on my lower buds!!!
