| From April on, the larvae hatch. First they suck juice from the fresh leaves and the shoots of their host plants. The larvae (nymphs) are light green to deep green in colour and have orange-spotted antennae. In the 2nd to 4th larval stage, they swop over to herbaceous plants (potatoes, beets, strawberries, etc. ). | | |

| The head is bright reddish yellow in colour with black compound eyes. The hairs on the antennae are light in colour. The legs are bright yellow and rounder and thicker at the joints. | | |

The average width of the females’ antenna segments is slightly smaller. From the 5th segment on, the males’ antennae are reddish. The wing covers (elytra) are slightly elongated, narrow rounded and at the tips are slightly trimmed. The exterior (outer edges) blends into a sharp angle. Their surface is granulated, covered in dots and has a weak sheen. | | |
|
| Adults reach body lengths of 7. 5-10. 5 mm. The upper surface of their bodies is densely covered with grey or brown hair and therefore appears grey although it is in fact black. The wing covers (elytra ) have a series of small indentations. The antennae are black and remarkably long. The larvae of these beetles develop in sandy soils. | | |

| ...s and yellow, grey-brown, yellowish-brown or brown in colour, with spots and irregularly distributed pits. The underside of the body is light coloured with dark spots. Between the front hips (on the 1st sternite) is a long crescent-shaped spike. The antennae are predominantly black with yellowish-white stripes on the 3rd to 5th segments. The 2nd segment is longer than the 3rd. The mouthparts form a proboscis. | | |
|
| Adult Eupeodes corollae reach body lengths of 7 - 11 mm. Their antennae are yellow-brown to dark brown in colour. The scutellum is hairy and light yellow in colour. The legs and hips are black and yellow. The abdomen is oval and has 3 yellow stripes, which run to the lateral edges. In the females these stripes are disco... | | |
|
| Adult Eristalis lineata reach body lengths of 11 - 15 mm. They resemble bees. Their faces are covered in white hair, which is divided by a stark black central line. There are also long hairs on their antennae. Eristalis lineata can be confused with Eristalis interrupta. | | |
|
| The head is is elongated at the front. The first two segments of the antennae are black, the third is yellowish-brown. The 2nd segment is ovoid to roundish in shape. The area between the eyes is whitish-yellow or yellow and is broken up by a grey-yellow central line. The compound eyes are positioned at a distance to each othe... | | |

| The hind wings are darker than the forewings. The head is bright reddish-brown and bears black compound eyes. The males have heavily feathered antennae. | | |

| ...th. Their bodies are oval shaped and have a black base colour. The head and pronotum are black to dark red or brown. In the male specimens the 11th antenna segment is sabre -shaped and four times the length of the previous two segments together. The antennae are reddish to yellow in colour. The head is standing upright and partially hidden behind the fore chest. The front tapered hips protrude. The elytra (forewings) are brown, reddish yellow or yellow in colour and covered with yellowish or light brown... | | |
