Red ladybirds, seen them, heard them, and read about them. But have you ever seen a yellow ladybird? And even if you have, have you ever wondered if, unlike their counterparts, the red ladybirds, they are poisonous?

Well, worry not, because today we are here to clear away any doubts.

Are Yellow Ladybugs Poisonous?

Yellow ladybirds, fortunately, like other species of ladybirds, are not poisonous to humans. They do not pose any harm or contain any toxins that could cause adverse effects on human beings.

However, it is important to note that they might not be the most appetizing thing to consume. As we have read and seen in our previous articles, animals often display a variety of colors to signal their unpalatability to predators.

As a precautionary measure, it is still important to wash one’s hands after touching them.

With all of this out of the way, let’s dive into the world of yellow ladybirds!

These variations include a range of body colors from cream to yellow to light orange.

These ladybirds possess 14 almost rectangular black spots on their elytra (wing covers), hence their name.

However, it’s common for several of these spots to fuse into larger markings, often taking the shape of an anchor.

They are entomophagous, primarily feeding on aphids, Aleyrodidae, Coccoidea, and even the larvae and eggs of some other insects.

As they mature, black spots become visible on their forewings, making them stand out even more. They are known to have a great appetite for bamboo aphids.

Giant Bamboo ladybirds emit a foul-smelling yellow-colored fluid as their defense mechanism.

3) Fungus-eating Ladybird

Scientific Name Illeis galbula
