Lizards are fascinating creatures with equally intriguing diets. Knowing which insects are safe and healthy for them to eat is critical, whether you already have one basking blissfully in its terrarium or are just starting to keep lizards. Many lizard species are insectivores, and a diet rich in live insects has a substantial impact on their overall health, development, and activity levels.
This article will go over the top five insects that are safe and healthy for lizards, as well as some helpful tips on feeding, gut loading, and avoiding common mistakes.
1. Crickets
Most lizard owners select crickets as their primary meal insect. They are affordable, readily available, and provide a significant protein boost. Crickets are available at most pet stores in Australia in a variety of sizes to suit different ages and types of lizards.
Benefits of feeding crickets:
- High in protein and fiber.
- Encourages natural hunting behavior.
- Fruit, vegetables, and calcium powder can aid with stomach loading.
Pro tip: Do not leave uneaten bugs in the tank overnight because they may attack sleeping reptiles or cause them distress.
2. Mealworms
Mealworms, another popular feeder bug, are particularly valued for their long shelf life. These fat-rich, wriggly beetles are an excellent source of nutrition, particularly for young or underweight lizards.
Feeding tips:
- The high fat content and tough exoskeleton make them unsuitable as a primary meal.
- Best shown with other insects.
- Before feeding, apply a calcium and D3 supplement.
3. Dubia roaches
Dubia roaches are becoming increasingly popular among reptile enthusiasts, particularly for larger reptiles such as bearded dragons and monitors. They are quieter and cleaner than crickets and less likely to flee.
Why choose dubia roaches:
- More protein than crickets.
- Less chitin, which helps them digest.
- If you breed your own feeders, they will live longer and reproduce more frequently.
These roaches are an excellent alternative for those looking to start a feeding colony in their home.
4. Waxworms
Waxworms are like lizard candy: sweet, velvety, and difficult to resist for many reptiles. However, because of their high fat content, they should only be used sparingly.
Use waxworms as:
- A rare treat—once or twice per week.
- A gadget to encourage eating in sick or picky lizards.
- A reward during management or training.
Though they should never replace a staple insect, they are excellent for rekindling a lizard's appetite.
5. Silkworms
Silkworms are rich in nutrients and gentle on your lizard's digestive tract. Though not widely available in pet stores, many Australian reptile owners are turning to online sources for these high-quality feeders.
Nutritional perks:
- Rich in essential amino acids, calcium, and protein.
- Soft-bodied, making them easy for all lizard types to digest.
- Less fat than mealworms and waxworms.
Gut-loading: why it matters
Gut-loading is the technique of feeding your insects nutritious foods before offering them to your lizard. This ensures that your reptile is also getting in those nutrients.
What to feed feeder insects:
- Sweet potato, kale, and carrot
- Commercial gut-loading recipes
- Bran or oats for fiber.
Don't give insects harmful foods like onions or citrus fruits, as these can transmit hazardous poisons.
Common mistakes to avoid
Even experienced reptile caretakers make blunders when feeding. Here are some things to remember:
- Overfeeding fatty insects: Mealworms and waxworms should be treated as treats rather than daily meals.
- Feeding wild insects: Garden bugs may carry parasites or poisons.
- Skipping supplements: Indoor reptiles, in particular, require calcium and vitamin D3.
- Wrong insect size: To avoid choking, feeder insects should be smaller than the width of your lizard's eyes.
Final thoughts
One of the most important aspects of reptile care is giving your lizard the right insects. Variety is key to keeping your scaly friend happy and healthy, from protein-packed crickets to nutrient-dense silkworms. Just bear in mind the bug's nutritional composition and feed according to your pet's specific needs.
Staying educated and offering a diverse diet can allow your lizard to enjoy a long, active, and flourishing life.
