DC Manga/Anime Case Help?

[Shinran]

There was this case I read when I started on the series. I don’t remember the title of the episode or chapter file set, but I do vaguely remember something about some sort of fake blood on the toilet. There was a scientific name for what was placed in the toilet. Everyone but Conan was fooled, I believe. I’m sure it was a Kogoro case, but I don’t know which one. If you know, I’ll be happy. Thanks. ^^

Phenolphthalein + ammonia dissolved in alcohol.
The alkaline ammonia turns the phenolphthalein pink, which in the dark looks more blood-like.

Yup, it's a Kogoro case. It's from Volume 35 Chapters 5-7, the Haunted House case. Or episodes 274-275.

I just re-read the case before I saw your thread

My bad, it's the phenolphthalein that's dissolved in alcohol, sorry 
You're welcome

Agreed. It's not possible with moth pheromones. Insect aggregation pheromones exist and people use them for insect control, but they only work well enough to attract a few bugs which alert farmers to any impending infestations so they have the time break out the real biological warfare instead of being caught off-guard. There is no way in hades to attract a windowful of moths in a few minutes.
There is a moth the aggregates in large numbers: Euxoa auxiliaris, the Miller moth (the caterpillars are called Army Cutworms). In Yellowstone National Park during the summer, they head for the mountains and aggregate under rocks there. Grizzly bears climb the mountains after them and eat them. The moths are actually a significant contribution to the bear's diet in the summer. One bear can eat 40,000 moths a day.
