This is a very interesting beattle.
Orden Coleoptera/Suborden POLYPHAGA/Infraorden Cucujiformia/Superfam. Tenebrionoidea/Familia Meloidae/Subfamilia Meloinae Ganglbauer, 1907/Tribu Lyttini/Gen. Berberomeloe (Bologna, 1989)/Berberomeloe majalis (Linnaeus, 1758)
Here some information from www.granadanatural.com
This is a species that goes through several larval phases before reaching the adult stage, in a process known as hypermetamorphosis.
Egg-laying takes place in a cavity that the female performs in the ground at shallow depths. At the beginning of the summer the first larvae, of small size, reach the surface and quickly look for plants in flowering to which they will rise to be located in the corolla of a flower. This larva of elongated form (similar to the silverfish) and has three strong nails in the end of each leg, reason why they are known as triungulinus. These nails allow a great grip on any insect that is posed by the flower. Although they must cling to the appropriate species of solitary bee, it is not uncommon for them to be transported by other types of similar insects, such as syrphids and bumblebees. It is for this reason that the clutches have hundreds of eggs. If the larva is able to grasp and be transported by the appropriate solitary bee to the nest or honeycomb of the same, this will have fulfilled the most complicated part of the cycle of the oilcan.
Once inside the nest, the larva feeds on a bee pupa and occupies the corresponding cell. From this moment on, its diet will be based on nectar and pollen provided by the solitary bee. When it has grown enough it will form a pseudopupa that after a while will give rise to a second larva of very different morphology from the previous one.
This new larva has a bigger, fatter body; it will spend most of its time feeding on pollen stored by the solitary bee in the nest or honeycomb. When it completes its growth it will pupate and after a time it will give place to the imago or adult. These appear from April to May, being from June in areas with higher altitude, as in Sierra Nevada. The metamorphosis process in which two or more different types of larvae are involved is known as hypermetamorphosis. In this case it behaves like a parasitic species.
As a defence mechanism Berberomeloe majalis exudes a few drops of a substance with an oily aspect (hence the popular name of aceiteras), which is very toxic and irritating, especially if it comes into contact with the mucous membranes and eyes. This substance is known as cantaridina that causes redness, rashes and irritation in contact with the skin. If consumed orally, it causes nausea, vomiting, diarrhea and irritation in the urinary tract and causes an erection of the penis, so it was mistakenly considered an aphrodisiac substance. For this reason this species presents these warning colors, also called aposematics.
