I wonder if the first larva is a first instar butterfly, possibly a swallowtail. I don't know what's available in Spain. The second pic shows pro-legs underneath that don't look 'beetley'. Also, the 'bird-poop' pattern is very common among first instar swallowtails. Otherwise, agreed. Aphids often turn hard, very round and light brown when parasitized, at least close to the time the parasite matures. These are really nice shots.
Hi relbugman and thanks for your response. I have often seen the Scarce Swallow butterfly in our garden and I have looked on the web for instars of this and have found a photo which resembles mine very closely. Here is the link:
There are a few on our young Pear tree so I will keep a close eye on their development and keep you updated.
