Unfortunately for our UK wild birds, natural sources of calcium are becoming harder and harder to find. With the heavy use of pesticides in agriculture and the reduction of natural habitat, birds & mamals are finding healthy calcium sources few and far between.
But……fortunately for them, the CALCI worm (Calcium Worm) is here!
Calci Worms are the larvae of the Black Soldier Fly (Hermetia illucens). They typically have up to 50 times the amount of calcium than other insects or worms and are suitable to feed to a wide variety of birds, insects, and mammals. They’re also particularly popular as a source of calcium and protein for fish!
Hedgehogs love meal worms, however, too many are not ideal, calci worms, however, have the natural balance they need and are far more suitable for our prickly buddies!
Meal worms are also a good food source, but what is the difference?
Mealworms are the larval form of the mealworm beetle, Tenebrio molitor, a species of darkling beetle. Like all holometabolic insects, they go through four life stages: egg, larva, pupa, and adult. Larvae typically measure about 2.5 cm or more, whereas adults are generally between 1.25 and 1.8 cm in length. Meal worms have a similar head shape to a caterpillar where as the Calci Worm has a pointed head, similar shape to a standard fly larvae (or maggot)
So, Meal worms Vs Calci worms!
Dried Mealworms are typically higher in protein; however, Calci Worms are much higher in fat and, of course, calcium. In order to keep your wild birds or mamals happy and healthy throughout the year you can either alternate between the two types of worms during different seasons, or mix the two together all year round!
Calci Worms are ideal to feed in the weeks leading up to breeding and egg laying seasons. The added calcium can aid in producing healthy, thick egg shells to keep growing chicks secure. Many birds don’t store extra calcium so it’s important that Calci Worms are offered as close to this season as possible.
During fledgling season and leading into the summer months, the high protein content in Dried Mealworms gives birds much needed extra energy whilst they moult and for growth.
