Ens trobem a una petita terrassa a Barcelona.
Hi creix camamilla que va germinar espontàniament.
Era d'esperar que tard o d'hora els pugons presents a la primera terrasseta serien atacats.
I així ha estat.
Però no com m'esperava. No han estat les vespetes, les qui els han liquidat.
Ha vingut un altre depredador.
It was likely that sooner or later the aphids in the first small terrasse would be attacked.
And so it was.
But not as I expected. It was not the wasps, who liquidated them.
Another predator has flown its way into my terrasse.
Hi creix camamilla que va germinar espontàniament.
I hi ha arribat pugó, que se n'alimenta.
En aquesta terrassa no s'utilitzen pesticides.
We are located in a small terrasse in Barcelona.
Chamomile popped up here spontaneously.
Aphids have also arrived and feed on chamomile.
In this terrasse I don't use insecticides.
A una terrasseta contigua hi ha farigola, també nascuda aquí mateix a partir de llavor.
Fa unes setmanes estava infestada de pugó, però ara només s'hi veuen desenes de carcasses de pugó, tot el que n'han deixat les vespetes parasitoides.
In another small terrasse next to this one, thyme grows, it also started here from seed.
Some weeks ago thyme was infested by aphids, but now all that remains of them are their mommies, a clear sign of parasitoid wasp attack.
Cadascuna d'aquestes carcasses marró era un pugó. Només en aquesta branqueta n'hi ha desenes. Per tant en total es compten per centenes.
Each one of these brown small sphere-like mommies was an aphid. Only in this thyme twig there are dozens of them.
I així ha estat.
Però no com m'esperava. No han estat les vespetes, les qui els han liquidat.
Ha vingut un altre depredador.

Another predator has flown its way into my terrasse.
L'aparició d'aquesta marieta de set punts ha coincidit amb la desaparició de molts pugons que tenia localitzats.
The entrance into scene of this ladybird has happened at the same time in which many aphids have vanished...
Una segona marieta també patrulla per la farigola.
A second ladybird patrols my thyme plants.
