Their year side by side

  • Pheidole pallidula : Hibernation: Nov – Mar, Nuptial flights: May – Aug

  • Tetramorium caespitum : Hibernation: Oct – Mar, Nuptial flights: Jun – Aug

Months for temperate Europe and the Mediterranean. The weather decides the exact days, so flights can come earlier or later where you live.

How to tell them apart

Pheidole pallidula

Light yellowish to reddish-brown workers of two kinds: small, quick minors and majors whose head looks far too big for their body. The majors carry strong, sharp jaws.

  • Tip Offer a few small seeds next to the sugar and insects: the big-headed majors crack them open so the whole colony can eat the soft part inside.
  • Tip They like consistently moist chambers. If the nest dries out too quickly, rearrange the setup so it holds moisture better: in a naturalistic setup, a piece of wood or a bark substrate helps.

Tetramorium caespitum

Tiny dark brown to blackish workers with fine ridges on the head and thorax, a smooth shiny gaster and a waist made of two small segments. A pair of short spines sticks out at the back of the thorax.

  • Watch out These ants are masters at finding gaps, so pick an acrylic or test tube-based nest whose layers fit tightly together, and check every join of a naturalistic enclosure.
  • Tip Give this fast grower plenty of protein: once the first workers are out, regular insects feed the queen and the brood.
