Researchers have yet to perform long-term studies on P. jacobsoni; like most hover wasps, P. jacobsoni has not undergone long-term observation so there is only limited information on their colony cycles.
Peneliti masih perlu melakukan penelitian panjang terhadap P. jacobsoni; layaknya kebanyakan tawon pelayang, P. jacobsoni belum pernah diobservasi dalam jangka waktu sehingga hanya sedikit informasi yang tersedia terkait siklus koloninya.
