⚠ Invasive here — plant a native instead USDA + GBIF

Mottled Spurge is flagged invasive in the U.S. These natives fill a similar niche — same growth habit, bloom season, height, and region — so you keep the look and feed local wildlife instead of spreading a problem.

❧ Caterpillar hosts ~7 caterpillar species

Euphorbia supports ~7 caterpillar species.

Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a modest genus.

Recorded feeding on Euphorbia in North America, including:

Chamaesphecia empiformis · clearwing moth Chamaesphecia tenthrediniformis · clearwing moth Cydia deshaisiana · Jumping Bean Moth Danaus plexippus · Monarch Episimus argutana · leafroller moth Erinnyis ello · Ello Sphinx

✦ Bees specialist-bee host · 1 bee visitor

Specialist native bees depend on it.

Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Euphorbia is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.
