What do mealworms look like when they grow?
Eggs hatch into larvae, called mealworms. They emerge milky white with slender, segmented bodies, which turn yellow-brown in a few days. The pests feed on their surroundings and grow to about an inch in length, shedding their skins several times in the process and contaminating stores of food.
Does a mealworm look like?
Description Mealworms are shiny and look like worms, although they are part of the darkling beetle group. Notes Larvae look like tiny yellow caterpillars and can grow up to 30 mm at maturity with very hard shell-like bodies.
What is the shape of a mealworm?
The mealworm is the larval stage of the darkling beetle. Anatomy: The tiny, white, bean-shaped eggs are about 2 mm long by . 9 mm wide. Larvae are dark yellow with brown bands; they are up to about 35 mm long, have a segmented body, six legs (towards the front of the body) and two antennae.
How do you identify a mealworm?
They are dark in color, have a hard shell and are about ½ inch long. Larvae: The common name mealworm comes from the appearance of the larvae (caterpillars), which are cylinder-shaped and about an inch long when full grown. Their coloration is yellow with brownish rings on the body segments.
How long can a mealworm live?
two years
A: Mealworms can live for over two years. They spend either one or two years as larvae and then turn into beetles.
How long does it take for a mealworm to turn into a beetle?
Two or three weeks after the mealworm has pupated, a mealworm beetle will emerge. This is known as a darkling beetle. The egg stage typically lasts 7-14 days but low temperatures and humidity can lengthen double this incubation time.
How do mealworms change over time?
Each mealworm eats a tremendous amount and grows a lot, molting (shedding its exoskeleton) many times as it grows. It then enters the pupal stage (this stage lasts from 2-3 weeks, up to 9 months, if the pupal stage over-winters). The pupa does not eat and seems inactive, but it is transforming itself into an adult.
What are mealworm adults?
Mealworms are the larval form of the mealworm beetle, Tenebrio molitor, a species of darkling beetle. Larvae typically measure about 2.5 cm or more, whereas adults are generally between 1.25 and 1.8 cm in length.
Can mealworms bite?
Do Mealworms Bite? No. Like superworms, mealworms do have mandibles, but they seem to be too small and weak to be noticed by humans or reptiles if biting is attempted. Mealworm beetles also do not seem inclined or able to bite.
How are mealworms different from all other insects?
Mealworms are holometabolic insects — AKA insects that develop in four distinct stages; egg, larvae, pupae, and imago (adult). Each one of these life stages is distinct from one another, making the transformation of egg to adult a complete metamorphosis. Other insects that are holometabolic include butterflies, moths, bees, and wasps.
What kind of life stage does a mealworm have?
Mealworms are holometabolic insects — AKA insects that develop in four distinct stages; egg, larvae, pupae, and imago (adult). Each one of these life stages is distinct from one another, making the transformation of egg to adult a complete metamorphosis.
How long does a mealworm pupa live as an adult?
The pupa is quite helpless and the only movement it can do is wiggle. This stage of life will last one to three weeks as the pupa transforms its organs and body into an adult. Adult. The final stage of the insect’s life is as the darkling beetle and lasts one to three months.
How big is a mealworm beetle when it is full grown?
Larvae typically measure about 2.5 cm or more, whereas adults are generally between 1.25 and 1.8 cm in length. The mealworm beetle breeds prolifically. Mating is a three-step process: the male chasing the female, mounting her and inserting his aedeagus, and injecting a sperm packet.

What does the pupa of a mealworm look like?
However, there are several changes going on inside it where it is actually growing into an adult. In the beginning, the pupa looks creamy-white in color, but slowly transforms to a brownish color. These pupae of mealworms look similar to the pupae of butterflies.
What does a yellow mealworm beetle look like?
Yellow mealworm adults look like typical beetles, and are not worm-like in appearance as their common name suggests. They are dark in color, have a hard shell and are about ½ inch long.
