Types of Insect Mouthparts - 4 specimens embedded in acrylic block

Four natural specimens, each representing different type of insect mouthpart, are embedded in a transparent, rectangular acrylic block. Each specimen is identified by an index:

1 - biting-sucking mouthpart, 

2 - piercing-sucking mouthpart, 

3 - siphoning mouthpart, 

4 - biting mouthpart.

The block is wrapped in a bubble pocket and packed in a cardboard box. Dimensions: 7.5 x 4 x 1 cm.

It is worth to know and remember that insects are the most diverse group of organisms on Earth, making up about 80% of all known animal species. There are about million described species, and scientists estimate that there could be up to 10 million in total. Insects play critical roles in ecosystems: they pollinate around 75% of flowering plants, decompose organic matter, and serve as a primary food source for many animals. Their ecological impact and contribution to biodiversity make them essential for the health of the planet.
