I did not realize the Asian Lady Beetle AKA Harlequin beetle, (note the white head) had eyes similar to flies & found this rather interesting. Did not know they could stink, leave stains or bite! Very interesting!
Can be a pest:
Inside they can omit a terrible odor & yellowish fluid they can secrete if disturbed. This fluid can stain surfaces on which they crawl such as walls or furniture. Can be aggressive & bite if they land on the skin.
Outside they are becoming a problem in vineyards, where they can end up being "collected" along with the grapes resulting in an "off" taste in the wine.
The Asian Lady Beetle was introduced as a biological control against crop pests. The larvae are larger than most native ladybird larvae & both adults & larvae consume aphids.
It is a ravenous predator of arthropod pests such as aphids, mites, thrips, scale & Lepidoptera eggs.
Benefit: It has contributed to a decrease in pesticide use on many crops & in orchards.
