Life Cycle of Indianmeal moth
Egg Upon oviposition, the eggs of indianmeal moth are tiny, oval, and initially pale, becoming darker as they mature. They serve as a protected developmental stage for the embryonic indianmeal moth.
Larva The larva, or caterpillar, emerges as a small worm-like indianmeal moth with a voracious appetite, growing substantially in size and molting several times before pupation.
Pupal Encased within a cocoon, the indianmeal moth enters the pupal stage, where it is immobile and undergoes a radical transformation, reorganizing into the adult form.
Adult Emerging from the pupa, the adult indianmeal moth displays wings and the ability to reproduce. Its coloration is typically brighter, and it seeks mates for reproduction.

Habitat Preferences of Indianmeal moth Through Different Life Stages
The eggs of indianmeal moth are typically found on dried fruits, nuts, and grains, as the females tend to lay them near potential food sources. Caterpillars, the larval stage of indianmeal moth, are often found within pantries or places where dry foodstuffs are stored since they feed on these items. Pupae usually reside within silken cocoons in quiet, undisturbed areas close to a food source. Adults prefer dimly lit environments and are usually spotted near infested items. Searching for indianmeal moth's different stages involves looking into stored dry foods, checking for webbings or boreholes in packaging, and inspecting pantry corners for cocoons.

How and Where Can You Find Indianmeal moth at Different Life Stages
Egg Indianmeal moth eggs are tiny and can be found laid in clusters on food products or packaging materials. Careful inspection of potential food sources under a magnifying glass may reveal them.
Larva Indianmeal moth larvae are relatively easy to find as they produce silken webbing in infested foodstuffs. Look for this webbing in grains, dried fruits, nuts, and other stored products to locate them.
Pupal Indianmeal moth pupae can often be found in close proximity to the infested food products. Check for cocoon-like structures made of silk and food particles within the pantry or storage areas.
Adult Adult indianmeal moth can be spotted by setting up light traps or pheromone traps at night near potential feeding or breeding sites, such as food storage areas.

Stored Produce Pest

The larva of indianmeal moth can inflict mild to severe damage on stored products like grains, nuts, dried fruit, cereals, and chocolate. They contaminate the food with webbing and excrement, making it unfit for consumption. The infestation can lead to considerable economic losses, and the larvae's feeding behavior promotes its spread and reproduction, aggravating the impact.
