New bearded dragon owners get told “feed insects and greens” and are left to work out the actual schedule by trial and error. The trial and error version usually goes wrong in one direction: too many insects, for too long, because insects are the fun, obviously-eaten part of the diet and greens often sit untouched in the bowl. The real schedule is less about a fixed number of crickets and more about a ratio that shifts hard as the dragon grows, from almost-all-insects as a hatchling to mostly-salad as an adult. Get the ratio and the frequency roughly right for the animal’s age and the rest of bearded dragon feeding looks after itself.
The schedule by age
A bearded dragon’s feeding needs change more over its first year than at any other point in its life, so age is the main thing to feed to.
Hatchlings and young juveniles, roughly up to four months old, are growing fast and need feeding most intensively: appropriately sized live insects once or twice a day, calcium-dusted every feed, alongside fresh finely chopped greens and vegetables available at all times, even if a baby dragon mostly ignores the salad bowl early on. From around four months to a year, insects drop to once daily as growth slows, with the daily salad becoming a steadily bigger part of what actually gets eaten. By the time a dragon is a year or so old and into adulthood, the pattern flips: insects become the occasional extra, typically every other day or two to three times a week, and a fresh daily salad becomes the main meal. An adult dragon that is still being fed insects once or twice a day, every day, the way it was as a baby, is being overfed on the wrong part of the diet.
Why the ratio matters more than the count
It is tempting to focus on “how many crickets” when the more important number is the balance between insects and plant matter, because that balance is what the dragon’s body is actually built around at each stage.
A growing hatchling needs the extra protein and calories that insects provide to support rapid growth, which is why insects dominate the early diet. An adult dragon’s growth has mostly stopped, and a diet that stays insect-heavy into adulthood delivers more fat and protein than an adult needs, alongside less of the fibre and varied nutrients that come from vegetables. The practical result of getting this wrong is a dragon that becomes overweight, which is a genuine welfare issue in captive bearded dragons and one that is entirely avoidable by shifting the ratio as the animal ages rather than feeding “the bearded dragon diet” as one static thing for ten years. A vitamin and calcium fortified pellet can round out the diet at any age, but it supplements the live insects and fresh greens, it does not replace either of them.
Getting the insects to the dragon
However often you are feeding insects at a given age, how you offer them matters almost as much as how many.
Live insects should be appropriately sized for the dragon, roughly no wider than the gap between its eyes, since anything bigger risks impaction or injury. Feeding tongs make offering insects easier and safer, keeping fingers away from a dragon that may lunge for a wriggling cricket, and they let you control exactly how much is eaten rather than tipping a tub of loose insects into the enclosure where uneaten ones can hide, stress the dragon, or even bite it back. Insects that are gut-loaded, meaning fed a nutritious diet themselves for a day or two before being offered, carry more real nutrition into your dragon than insects straight from the tub, which is covered in more depth in feeding your reptile the right diet and supplements.
None of this works without the other side of bearded dragon care holding up its end. A dragon kept too cool will not digest food properly regardless of how well you time the meals, which is why why UVB and heat matter is worth reading alongside this, and calcium dusted onto insects is only useful if the dragon also has the UVB it needs to use that calcium, the two work together rather than one substituting for the other, as covered in signs of metabolic bone disease in reptiles.
A bearded dragon fed on the right schedule for its age, insects shifting from daily staple to occasional extra as it grows into an adult that lives mostly on greens, is one of the more straightforward reptiles to feed well. The mistake almost everyone makes once is keeping the baby ratio going for an adult, and the fix is simply remembering that the diet is supposed to change as the dragon does.
Common questions
- How many times a day should I feed my bearded dragon?
- Hatchlings and young juveniles, up to around four months, do best with insects offered once or twice daily plus daily fresh greens available at all times. From four months to a year, insects drop to once a day. Adults over a year typically eat insects every other day, or two to three times a week, with a daily salad as the main event.
- Why does my adult bearded dragon refuse insects some days?
- This is usually normal rather than a problem. Adult dragons naturally eat fewer insects than juveniles, and a healthy adult that is getting a good daily salad does not need insects every single day. Persistent refusal of both insects and greens together is different and worth checking against husbandry and health.
- Can I overfeed a bearded dragon on insects?
- Yes, and it is one of the more common feeding mistakes. Too many insects, especially in an adult, leads to obesity and an imbalanced diet, since insects are higher in fat and lower in the fibre and nutrients a dragon gets from vegetables. The ratio should shift toward plant matter as the dragon grows, not stay insect-heavy for life.
- Do I still need to dust insects with calcium if I feed a vegetable-fortified pellet too?
- Yes. A fortified pellet is a helpful supplement to the diet, not a replacement for dusting live feeder insects with calcium. Feeder insects are naturally low in calcium regardless of what else the dragon eats, so calcium dusting stays part of the routine at every life stage.
