We've been hearing about it and have seen photos asking people to report any sightings. I haven't heard of any turning up locally as yet, but imo, it's only a matter of time. It's incredible what kind of damage these alien species can do. The other day, I was reading a research paper on Harmonia axyridis, the Asian lady beetle, which is the introduced species that is sold for bio-control. In addition to target insects such as aphids, the lady beetles also kill non-target insects such as some of the native species of lady beetles. Worse still, one of the researchers who has been doing a lot of work on H. axyridis, has found that one H. axyridis can consume about 50 Monarch butterfly eggs in about 24 hours in laboratory conditions. Considering how predatory this species is, I'd say there's probably a good chance that they're eating at least some Monarch eggs under field conditions. Anyhow, it's rather a drag when introduced species start to impact on non-targets. croc
