Some of the loss in diversity and biomass of native insects has been masked (and partly caused) by invasions of non-native species. This is especially true of ladybugs, a diverse group which in some areas has been almost completely replaced by a single non-native species.

In much of the US, the native ladybugs have been largely replaced by a whole suite of non-native species. Someone who is not looking closely might think ladybugs are doing just fine.
