Yes, cicada insects are protein-dense, with 45–65 g per 100 g dry weight, or about 13–20 g per 100 g cooked.
Curious about the buzz around edible insects? This guide breaks down how these singing bugs stack up for protein, how serving size changes the numbers, and what to know about safety and taste. You’ll get clear figures, practical prep pointers, and a quick comparison to everyday foods so you can decide if they fit your goals.
Are Cicadas A Protein-Dense Snack? Evidence & Ranges
Across entomology and food science papers, dry-weight protein for cicada species lands in the mid range for edible insects. A recent lab analysis of cicada flour reported about 63.5 g protein per 100 g on a dry basis. A land-grant extension summary puts cicada protein near 47% of proximate content on dry matter. Broad reviews of edible insects place many species between about 20% and 76% protein by dry weight, depending on species and life stage. On a cooked “ready to eat” basis with moisture, that figure settles closer to the teens per 100 g, which lines up with values home cooks see after roasting.
| Item | Basis | Protein (g/100 g) |
|---|---|---|
| Cicada flour (lab analysis) | Dry | ~63.5 |
| Cicadas (extension summary) | Dry | ~47 |
| Edible insects (review range) | Dry | ~20–76 |
| Chicken breast, cooked | Fresh | ~31 |
| Beef, cooked lean | Fresh | ~26 |
How Serving Size And Moisture Shift The Math
Numbers swing with water loss. Whole bodies hold a lot of moisture when cooked. When you grind and dehydrate into a flour, the dry matter fraction rises, so protein per 100 g climbs. That’s why a spoonful of insect flour looks protein-packed on labels while a plate of sautéed nymphs reads lower per 100 g. The food is the same; the water isn’t.
To keep estimates grounded, match like for like. Compare dry powders to other dry powders, and compare cooked whole insects to cooked meats. If you’re tracking macros, weigh what you’ll actually eat and use values that match that form.
What The Amino Acids Look Like
Research on cicada tissues shows a spread of protein fractions between about 10 and 75 kDa, a pattern seen across edible insects. Reviews report a solid mix of indispensable amino acids such as lysine and threonine, with aromatic pairs like phenylalanine plus tyrosine also present. That balance helps round out cereal-heavy diets where lysine can lag.
Safety, Allergies, And Who Should Skip Them
Cicadas are arthropods. People with crustacean allergies can react to chitin-associated proteins and tropomyosin-like allergens found across arthropods. The U.S. Food and Drug Administration has warned seafood-allergic consumers to avoid eating these insects. If you’re managing food allergies, treat cicadas the same way you’d treat shrimp or crab: steer clear, and check cross-contact in kitchens that fry or roast mixed items.
Basic food hygiene still applies. Harvest away from pesticide spray zones or heavy traffic, rinse thoroughly, blanch briefly, then cook through. Skip wild harvest for young children, pregnant people, or anyone who needs stricter risk control at mealtime.
Cicada Protein Content — Practical Ranges
Here’s a simple way to estimate protein in the form most home cooks use. For dehydrated pieces or flour, use the dry-basis values from lab work. For roasted whole insects, drop the number to account for water. A common kitchen estimate is that roasted whole bodies land near one third of the dry-basis figure per 100 g of food on the plate.
Quick Method To Estimate A Serving
Take the dry-basis figure (say, 60 g per 100 g dry). If your batch is roasted whole and not brittle-dry, divide by about three. That gives near 20 g protein per 100 g cooked weight. Scale to your portion size. If you serve 50 g roasted, that’s near 10 g protein. If you add a spoon of flour to batter, use the dry number directly.
How They Compare On Calories And Fat
Roasted whole cicadas are moderate on calories and usually come with a trim fat profile. Dry powders concentrate both protein and fat, so calories per 100 g rise. Compared with chicken breast, roasted whole insects are leaner on average. Compared with beef, they can be lighter on both fat and energy when served plain. Seasoning oils can double calories fast, so weigh the pan drizzle if you track energy intake.
Micronutrients Worth Calling Out
Beyond protein, studies report polyunsaturated fats including EPA present in both nymphs and adults. You’ll also see minerals like iron and zinc in ranges comparable to other edible insects. Exact values swing with species and life stage, but the overall picture points to a nutrient-dense animal food with a compact footprint.
B vitamins show up in modest amounts, and calcium can appear when exoskeleton pieces stay in the dish, though the figures vary with molt stage and how thoroughly you trim before cooking.
Field-To-Fork: Sourcing And Handling
If a local emergence brings a bumper crop, the safest option is to skip roadside collection and buy from a licensed supplier when possible. If you do gather, pick wooded areas away from spray records, bring a clean container, and keep the haul cold. At home, rinse, remove wings and legs for a smoother bite, blanch in salted water for two to three minutes, shock in ice water, drain, and pat dry. From there, roast at a moderate oven temp until crisp edges form, or pan toast in a dry skillet before seasoning.
For longer storage, freeze blanched bodies in a thin layer so they don’t clump, then portion into bags. For flour, dry thoroughly in a low oven or dehydrator and mill in a clean grinder reserved for foods. Label with date and batch notes so later recipes are easy to repeat.
Flavor, Texture, And Easy Uses
Freshly molted “teneral” bodies are soft and mild. Fully sclerotized adults turn nutty and toasty after heat. Common uses include taco fillings, rice bowls, garlic-chile snacks, and grinding into flour for batters. A light marinade with citrus and herbs keeps the profile bright. Don’t drown them in heavy sauces the first time; taste the ingredient itself.
Pair with citrus, chilies, fermented soy, or toasted seeds. In baked goods, a 10–25% swap of wheat flour for insect flour lifts protein without wrecking structure.
Evidence And Further Reading
Global food agencies and peer-reviewed reviews catalog the protein ranges and supply chain notes for edible insects. See the FAO overview of edible insects and broad reviews by Rumpold and Schlüter for dry-basis protein spans across orders. Recent species-level work on cicada flour and stage-specific profiles helps explain why numbers vary across life stages.
Serving Estimates And Macros
The table below gives ballpark protein, calories, and fat for common kitchen portions. Values assume minimal oil and plain seasoning. Actual numbers vary with species, moisture, prep time, and whether you trim wings and legs.

Who Might Like Them
Home cooks chasing a compact protein source enjoy the nutty flavor and easy prep. Hikers mix roasted pieces with nuts for a trail snack. Bakers use amounts of flour to lift protein in quick breads without the grainy feel of some plant powders.
Costs, Access, And Labels
Fresh insects are seasonal and local in many areas. When retail stock is available, price per gram of protein depends on whether you buy whole frozen bodies or milled flour. Whole products tend to be cheaper per serving, while specialty flours cost more but slot neatly into baked goods. Labels may list values on a dry basis; match that to how you plan to cook.
For home batches, exact macros shift with time in the oven and the ratio of soft tenerals to older adults. If you need repeatable nutrition, choose a packaged item with a full panel and keep your prep consistent from week to week.
Limitations And Trade-Offs
Supply is seasonal in many regions, labeling can be inconsistent, and values differ by species and stage. If you need highly standardized nutrition with tight tolerances, stick with items that have a full nutrient panel from a regulated producer. If you’re adventurous and flexible, modest swings in macros won’t matter.
Bottom Line: Are They Worth It For Protein?
If you want the most protein per gram, dry powders win. If you prefer a whole-food snack with crunch, roasted bodies deliver a respectable amount plus minerals and omega-3s. Keep allergy cautions in mind, match dry to dry and cooked to cooked when you compare, and use the serving table to plan a meal that fits your targets.
