Pheidole californica are is one of the only native Pheidole from Canada, living in a 150km stretch along the Okanagan Valley. Colonies eat just about anything, and grow very quickly if heated and fed frequently. Major workers have large heads used to crack seeds and tear through insect parts. They are particularly notable for the large differences between the "Big-headed" majors and the smaller minor workers.

Pheidole californica is a close relative of Pheidole pilifera, is a granivorous species, and can be often found with lures of walnut and many seeds. These ants should be kept hot to maintain growth, and hibernation is not required. Minor workers range from 1-2mm, and major workers range from 4-5mm, with queens reaching close to 7mm.

Colonies should be kept at above 28 degrees Celsius with humidity levels above 65%.

When it comes to proteins, Pheidole californica will take almost any protein source most feeder insects such as, fruit flies, crickets, mealworms, superworms, surinam roaches, and discoid roaches. It is generally recommended to feed larger prey items pre-killed because of their small worker sizes. Colonies will most likely have issues taking down large prey items. Pheidole californica have been observed to collect seeds and eat them in the wild. It is acceptable to feed them diiferent types of seeds such as dandelion seeds, walnuts, and almonds.
Air humidity: Pheidole californica should be kept at humidity levels around 65%.

Test tube inserts are upgrades to the test tube setups provided. If purchased, they come with a dark hood to lower light levels for the colony, an insert which provides a living space, and a feeding insert to provide food for the colony.

Ungrouted inserts are a blank plastic insert which helps provide a more suitable space for the ants to grip (as opposed to glass tubes), while grouted inserts are bedded with a substrate which helps distribute humidity more evenly throughout the test tube, and helps certain ants create their cocoons more easily. Overall, grouted inserts are more comfortable for the ants.

You will NOT need an insert for colonies in test tubes, but it does help for certain species. IF you are moving the ants into a nest immediately, do NOT get a test tube insert.

This species comes from more tropical areas than Canada, and are not cold-tolerant. Thus, we will not ship them in the winter

Just a warning, we will NOT ship live ants into the US unless the receiver has a permit. If such an order is made, it will be refunded, minus a 10% processing fee and restocking fee
