The Big Dikkopje.
The tadpole is a common, mobile butterfly that lives in a variety of sheltered, fairly moist grasslands and bushes, such as damp heather with pipe straw, grassy bushes in grasslands, forest clearings and along forest edges. The gutter tadpole has remained stable in the Netherlands throughout the twentieth century. The butterfly flies in one generation from early June to mid-August. The males often conduct patrol flights in the morning. In the afternoon they show territorial behavior. The female spends a lot of time resting in the sun.

The underside of the rear wing is yellowish with light spots. The male has a distinct scent stripe on the top of the forewing. The female is generally larger.
The Zwartsprietdikkopje.
This small, common butterfly is found almost everywhere in the Netherlands. It is only scarcer in parts of the Dutch river area. The Dutch distribution has hardly changed in the period from 1900 to 1990, but after that the species expanded. The Zwartsprietdikkopje appears in July and flies until the end of August.

The male has short straight, unobtrusive scent stripes that run parallel to the veins on the forewings. The wings are light brown to yellow with no markings on the top of the wings. On the underside of the forewings, the wing tip has the same color as the rest of the wing. The tips of the antennae are always black.

The Geelsprietdikkopje.
A fairly rare butterfly that mainly occurs in the east of the Netherlands (especially Drenthe, the Veluwe and South Limburg). Its distribution area has slowly but steadily decreased since the 1990s. This species is often confused with the Zwartsprietdikkopje. The Geelsprietdikkopje is distinguished by the yellow-brown underside of the end of the antenna.
The butterfly flies from mid-June to the end of August.

The male has inconspicuous, slightly curved scent stripes. The female is bright orange but the underside of both sexes is the same with little variation between individuals.
The Mallow tadpole.
In the Netherlands, the highly mobile butterfly is seen very irregularly and has been reproducing in South Limburg since 2009. The species occurs in dry, warm sparsely overgrown grasslands, bushes and roadsides. The butterflies fly in two generations, sometimes three, from late April to early September. They have coarser markings on the top of the wings than the resembling brown tadpole. The females deposit the eggs individually on the tops of leaves of various mallow species.
