One fascinating aspect of the wall anchor butterfly's life cycle is the metamorphosis they undergo. Starting their lives as eggs, they hatch into caterpillars, or larvae, which are voracious eaters. During this stage, they consume the leaves of specific host plants, gathering the nutrients essential for their growth. The caterpillar phase is often marked by vibrant colors that, paradoxically, serve as a warning to hungry predators about their potential toxicity. After a period of rapid growth, the caterpillar enters the pupal stage, transforming within a chrysalis. This metamorphosis is a remarkable process, symbolizing change and resilience; it is during this stage that the caterpillar's body is restructured, allowing it to emerge as a stunning butterfly.

Expansion anchors are designed to expand when the resin cures, providing a strong hold in soft or friable substrates such as concrete or masonry. Plug anchors, on the other hand, rely on friction to hold the blockwork in place and are suitable for harder substrates such as brick or stone. Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure holdresin anchors for blockwork.
