Lady beetles are generally good bugs. However, these are Asian lady beetles and while they do eat aphids, they also push out native species. Asian LB also enter structures to overwinter while native species primarily overwinter outside in leaf litter, wood piles, etc.
Asian LB can be an absolute nightmare. Many years ago when I was in WI, there were a couple years of very high populations that caused major problems for anybody with an older, "leaky" house. If they get in your house, most will die in the walls, attic, electrical boxes etc. the problem then is that come spring you will have an outbreak of larder beetles that move in to eat the dead beetles.
One couple with a newborn baby, put him down for a nap, came back a couple hours later and found the entire crib, blankets and baby covered with crawling beetles. They called me looking for solutions, and there wasn't much they could do other than move out, wait for cold weather and do a massive amount of spraying inside and out .
That year they were so bad in areas that we couldn't walk and talk around the research farm without beetles getting into your mouth and crawling all over you. If you walked outside, there would be dozens crawling over you in minutes. If you grab them with your fingers, they release a chemical that smells bad and tastes even worse.
In rural areas, you typically see them coming off soybean fields after harvest when days are warm and sunny with cooler/cold nights.
. Had to look up torus. I know what you mean though. Blackberries never bothered me, but mulberries are another thing. My black raspberries have thorns. Does that mean they are wild?
