Pheidole pallidula (Big-headed Ant)
The European Big Headed Ant is renowned for displaying hight activity levels, aggresive/swarming behaviour as well as a large degree of polymorphism. When keeping Pheidole pallidula, you'll immediately notice the sheer difference in size between the average worker ants and those of the soldier ants. Not to mention that the soldiers' mandibles rival those of the queen!
The yellow/orange colouration can be especially appreciated in the soldiers and queens whereas workers tend to be a darker orange/brownish colour.
In addition to their interesting morphology, colonies of this species have been observed to create several satellite nests in one single habitat! These are often formed by large numbers of workers and brood. Sometimes a queen or two will be found too, although this is quite rare! It's thought that this behavioural adaptation increases the likelihood of survival in the wild!
Lastly, whilst the general care of this species is relatively easy, it's important to note that they are great escape artists due to their small, lightweight nimble nature. Therefore, a reliable escape prevention system should be in place.
Otherwise, a great, hardy and active species to begin the hobby with or add to your existing collection.
It is illegal and strictly frowned upon to release any non-native ants into the wild.
