How to repel the milk-sucking butterfly or Iphiclides feisthamelii?

But it must be said about it that, although it is almost always harmless (in fact, all insects and microorganisms are if they are in their natural habitat), it does not hurt to have it watched just in case. Then I’ll tell you why.

What are their characteristics?

It is a ditrisio lepidopteran belonging to the Papilionidae family that lives in Spain, Portugal, southern France, Morocco, Algeria and Tunisia. The adult measures between 35 and 42mm, and has yellowish-white forewings with black bands, and hindwings with tail-like extensions, with metallic blue scales at the base. The males are larger than the females, and are somewhat darker in color.

Their life cycle is characterized by the two or three generations that can emerge per year, which adds up to between 2 and 6 new milk-sucking butterflies, since the females only lay 1-2 eggs at a time.

What symptoms or damage do they cause to plants?

Once the larvae hatch, they feed on the leaves of the Prunus, especially these species: Prunus dulcis (almond tree), Prunus persica (peach tree ) and Prunus domestica subsp. insititia (wild plum).

Apart from these, there are also others that can be affected, and they are Pyrus communis (pear tree), Malus domestica (apple tree) and Crataegus oxyacantha. For this reason, we will see the symptoms and/ or damage that it causes on the leaves, which will appear nibbled or with small holes, as well as with a progressive yellowing.

How does it repel?

If we grow some of the species that we have mentioned, it will be interesting to take some ecological measures to prevent them from being affected by  Iphiclides feisthamelii.

For that, we can make a garlic decoction every 15 days, then we pour the resulting liquid into a container and then place it near the plant that we want to protect.

So I’m sure it won’t come close , but since we won’t harm it, we can enjoy its beauty.
