Does anyone know what exactly is inedible in Colorado potato beetles and why? Does anyone eat them at all?

He offered them to his praying mantises. They didn't catch it. He cut it in half and offered it again. The mantis ate the whole inside, but did not touch chitin.

Their hemolymph is poisonous to other invertebrates.

Who will eat the bug?

Attempts are being made to regulate the number of Colorado Potato beetles using entomophagous insects, in particular with the help of predatory beetles Podisus maculiventris and Perillus bioculatus. Specialized predators (for example, the egg parasite Edovum puttleri) have also been found in the home of the Colorado Potato beetle. Bedbug larvae are released to potato crops during the mass oviposition period of the Colorado Potato beetle, and they destroy the eggs, thus reducing the number of pests. However, when mass releases of entomophages stop, the Colorado Potato beetle quickly regains its numbers.

I wonder why the birds don't touch the Colorado potato beetle, does the bright color really scare you away? Because Colorado potato beetles accumulate toxic solanine alkaloids in their bodies, which are found in the shoots and leaves of solanaceae, they are inedible for most birds and animals.
It is believed that only guinea fowl from the age of four months with an appetite eat the Colorado potato beetle.

these beetles also eat the larvae. I don't remember about imago.

If I remember correctly, the beetle's hemolyph accumulates solanine.
By the way, in Moldova they said that the Colorado potato beetle is well eaten by pheasants. I don't know if this is true, because the information came from local residents.

Okoem and I also touched on this issue the other day smile.gifPheasants eat them, but how many of these pheasants!!

There is also information from Moldova (from Mr. Zacharias Nekulisianu, if I'm not mistaken). Already outdated truth very much.. In general, in North America, some Lebia sp.are used to eat Colorado potato. Therefore, there are no special problems with Colorado. They tried to bring and breed these swans from us, but it didn't work out.

So the funny thing is that the hemolife mantis just ate! And still alive! When should I die if it is poisonous? But I didn't touch the covers...

Turkeys eat them well.

As I understand it, adult female tree mantises eat anything from ladybirds and Colorado potato beetles to crunching hornets and dragonflies.
